A subscriber identity module or subscriber identification module (SIM), widely known as a SIM card, is an integrated circuit that is intended to securely store the international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices (such as mobile phones and computers). Gold nano slot antennas are composed of two-dimensional (2-D) punctured rectangular slots of h = 150 nm, l = 60 μm, p = 10 μm, and d = 40 μm, where h, l, p, and d indicate the height, length of slot, and adjacent distances between neighboring slots, respectively, fabricated by combinatorial process of an e-beam lithography and a lift-off.
DSO Nano v3 is a portable digital storage oscilloscope. Based on a 32-bit ARM Cortex-M3 microcontroller, it is equipped with 320*240 color display, USB port and recharging function. It is compact, simple to operate; meets the basic demands of school labs, electrical repairs and engineering. The version 3 of DSO Nano differs from version 2 in that it does not use a white plastic case. Instead, it uses a black metal case which is more durable and strong.Features¶

Note: My device (Serial E1C5A0C1) does NOT have the indicated ’TF card slot’. There is no slot in the metal case and even if you open the case, there is no connector on the board (nor even a place to have put a connector).Usage¶Basic Operation¶
Left/Right buttons are mainly used to navigate through menu items. The selected menu item will be highlighted; its corresponding screen element will blink. Press UP/Down buttons to adjust. The OK button controls display/hide markers or confirm operations.
Pressing A (Run/Stop) Button once will freeze the current display. Press ’A’ again to resume. The B (Shift) Button is used for quick functions.
Throughout this text, adjustable items will be labeled in red.User Interface Overview¶
The screen is broken into a central display area and 3 operation bars around it. The menu on the top provides the most frequently-used adjustments to signal display. The status bar on the bottom provides precise measurement results and monitoring status. Adjust more advanced functions with the column of function icons on the right.Zooming on Signals¶
Move the cursor to the Vertical Scale and Time Base to start exploring the signal display. Press the up/down buttons to adjust the voltage/div or time/div. Each “div” is a grid unit ’division’ of the screen; count the divisions to estimate a quick measurement. The vertical scale ranges from 10mV/div to 10V/div. The time base ranges from 1uS/div to 10S/div. Beware that in the larger time bases the display may look frozen, since 10S/div means it takes 120 seconds to refresh whole the screen (12 divs wide).
The waveform might be out of the range of the display even in the appropriate voltage/div setting. You can change the Y position to move the waveform up and down to center the wave onscreen. The Y position marker indicates 0V for your reference.
Press button A to freeze the current display (setting the status to HOLD) and press again to resume refreshing (status RUN). With the status on HOLD, you can select the T0 icon and press the up/down buttons to pan back and forth. Press the OK button to display or hide the X position marker (a yellow dotted vertical line).Triggering Modes¶
The Nano has six triggering modes, accessible in the top left corner of the screen. These are:
AUTO: Always refresh the display, and synchronize when triggered. NORM (al): Display synchronized waveform when triggered, and blank if not triggering. SING (le): Display triggered waveform and hold, then blank again before triggering. SCAN: Repeatedly sweep waveform onscreen left to right. NONE: Refresh unsynchronized waveform ignoring triggering. FIT: Automatically adjust vertical and horizontal scale to display waveform. Comparison table of the triggering modes Mode Trigger Display Waveform Synchronization Example Applications AUTO Yes Always Yes General use NORM Yes Triggered Yes Only watch periodic signals SING Yes Triggered Auto-hold Capture a random pulse SCAN No Always No Keep monitoring signals NONE No Always No Watch an unsynchronized waveform FIT Yes Auto-adjust Yes Easily watch periodic signals
To set the triggering level, move cursor to Vt = ??.?mV and press the up/down buttons. Press OK to display or hide the trigger level markers (horizontal green dotted lines). To fine tune triggering, you may tweak the trigger sensitivity range TR and the trigger type. By default the trigger type is set to up S which means the trigger will fire when the signal crosses from the lower trigger line to the higher line. Down S will likewise trigger on a falling signal edge.
This could prevent mistaken triggering caused by noise, especially while measuring fast low-amplitude signals. If you set the sensitivity to 0, where the two trigger level markers overlap each other, you get level triggering. Please refer to Wikipedia for more informaiton on oscilloscope triggering.Measurement¶
Auto measurement is useful for quickly exploring signal characteristics. Measurement options include frequency, cycle time, duty cycle, peak voltage, RMS voltage, average voltage and DC voltage. Please note that frequency, cycle time and duty cycle can only be measured while triggering.
To get a more precise measurement, use the measurement markers. T2 and T1 control the time markers, the two vertical dotted lines. A precise time difference between two marker positions is displayed in ’time measure’ near bottom of the screen. The V1 marker and V2 marker can be adjusted directly from the ’voltage measure’ result panel (’V1-V2=? V’) at the bottom center of the screen.
Pressing the OK button in a menu item will hide or show the corresponding line onscreen.Waveform Storage¶
Waveforms can be saved to an mirco SD card or loaded to the display. You need a micro SD card to do this (not included). Please note that SDHC cards (high-speed cards larger than 2 GB) are not supported for now. Follow the below steps to set up your microSD card:
*Make sure your SD card supports SPI mode. (Max.menory: 2G)
*Format your SD card with the FAT16 filesystem.
When the microSD card is prepared, the FS (file save), FL (file load) and SI(image save) icons are enabled. Press the OK button on FS to save a waveform, or on FL to load the waveform from the microSD card. Also you could select **SI **for saving oscillogram in PNG format.Signal Generator¶
The 3.5mm audio jack under the mini USB port is used for the signal generator. It outputs a square wave from 10Hz to 1MHz. Frequency can be adjusted via Fo (’frequency out’). The peak voltage is the same as the supplied power, or approximately 3.7v if powered from battery, and 5v when powered by USB.Power Supply¶
The DSO Nano can be powered by the internal 500mAh LiPo battery or by the external mini-USB port. Charging takes about 2 hours 20 minutes to reach 4.12V. A brand-new unit can only run about 1 hour by battery, but the battery life will be extended after the LiPo battery is fully charged.Firmware Upgrades¶
To upgrade firmware, please perform following steps:
*
Download the latest applicable firmware to your PC.
*
Simultaneously press ’D’_own Key’ ’_and turn on power supply, enter DFU firmware upgrade mode.
*Use USB cable to connect DSO Nano v3 to your PC, a removable disk named DFU V3_11_A will appear on your PC. Copy the hex firmware to the root directory of your disk. After the extension of the firmware changes from “hex” to “rdy”, restart DSO Nano v3, thus firmware is upgraded.
NOTE that if there are multiple hex files (e.g. the BenF firmware) you must copy EACH file ONE at a time and wait for it to change to ’RDY’ before you copy the next one. So, if you have file1.hex and file2.hex then the process would be:
*
Copy file1.hex
*
Wait for file1.rdy
*
Copy file2.hex
*
Wait for file2.rdy
Under windows you will see the ’drive’ disappear after you copy each hex file and reappear with the rdy file.FAQ¶
*What is the hardware version and firmware version of DSO Nano v3 ?
DSO Nano v3 is of hardware v2.6 and firmware app v2.6 , you could find them on Resources.
*What is the main difference between DSO Nano v2 and v3 ?
Acutall, both of they are the with same hardware and firmware, also they of the same version of DFU which is used for upgrading firmware. So the main difference is the shell, DSO Nan v3 is with black metal shell instead of the white plastic shell on DSO Nano v2.Resources¶

You’ve got a swanky new phone, you want to put your old SIM card in and you’ve realised it doesn’t fit…. Alternatively you’re pretty new to smartphones and don’t have a clue what the SIM card is or where it even goes. This predicament isn’t unheard of but fear not, it’s all simple to sort out.
For those unaware, SIM cards are supplied by your smartphone service provider, such as BT Mobile.What does SIM means?
SIM stands for Subscriber Identity Module.
SIM cards are effectively mini circuit boards which identify your service provider and your mobile phone number. To find out more read our feature: How does a smartphone SIM work?
But as technology has advanced, the size of some SIM cards has gone down. In the UK three different types of SIM card now exist.
We talk you through each one and where you might find the SIM card slot to get your phone up and running.
Standard SIM Card
The standard SIM card is the original SIM and largest of the three. Standard SIMs are mainly used on older phones these days such as the Samsung Galaxy SII but also very basic phones such as the Nokia 105.
This SIM measures 25x15mm.
Micro SIM card
The Micro SIM card is essentially a standard SIM card with the extra plastic around the circuit board trimmed off.
This SIM is more likely to be used for smartphones introduced from 2010 till today, such as the Galaxy S5 and LG G4.
Some Micro SIM cards are attached within a Standard SIM-sized unit which you can pull off. This SIM is known as a Combi SIM as you can use it for both.
Micro SIM cards measure 15x12mm.
Nano SIM card
The Nano SIM card is the most recent type of SIM card which only measures 12.3x8.8mm. It’s used for newer smartphones, such as the Samsung Galaxy S9.Where do I find the SIM card slot on my smartphone?
The hardest part of installing a SIM card can be finding where it has to go in the first place. Your phone’s instruction manual should tell you where you can find it. If it doesn’t have a manual, visit the manufacturers website.
If you’re still struggling it’s probably in one of these places:
1. Behind the battery
The majority of older phones have their SIM card slot behind the battery.
Remove the phone’s outer case and take the battery out. Look for an empty slot and a SIM card icon.
If it’s something like the slot above, all you have to do is lay it flat and slide it behind the small metal bar.
Ensure that your SIM card is facing down so that the circuit touches the metal pins on the phone.
2. Next to the batteryNano Signal Slot App
Some SIM card slots can be found near the battery, which will require you to remove your phone’s outer case and the battery to fit it in.
As you can see in the image above, you’re looking for a small slot where the SIM card can fit.
Make sure you push it in so that the circuit can touch the metal pins. Usually the perfectly straight part hangs out of the bottom until you put the battery back in.
3. The hidden outside slot
Some smartphones feature SIM-card slots on the outside, so there’s no need to take the back off.
However, you may need to use a small tool that looks a bit like a blunt pin to push the SIM holder out. The tool should come with your phone when you buy it.
The slot holder can be found around the edge of your smartphone like above and will have a hole.
Put the tool into the hole and the holder will pop out, allowing you to place your SIM card inside and put it back in. Just make sure you keep the tool safe.
Don’t get confused with the microSD slot
The microSD slot is for microSD cards which you can use to expand your smartphone’s storage capacity for pictures, apps and more. The SIM card and microSD card have nothing to do with each other, but you may get their slots mixed up as they look quite similar.
Usually, you’ll find a microSD logo like below to tell you where micro SD card goes.Nano Signal Slot BoosterI’ve got the wrong SIM size for my phone - what should I do?Nano Signal Slot Games
You can speak to your service provider and they will send you out a replacement SIM card, BT Mobile customers need to go to bt.com/replacesim.
Alternatively, you can do a bit of DIY and chop your SIM down to size yourself. Be careful – you don’t want to break your SIM.
