Kit & Manual By Steven Vagts Z-100 LifeLine Insert, Issue #138 DSO150 Oscilloscope Kit Description: The DSO150 Oscilloscope is a bigger brother to the DSO138 discussed in an earlier issue. It is another inexpensive low-speed miniature oscilloscope with 2.4" color TFT LCD (320 x 240 dot matrix, 262K color display. Based on the ARM Cortex-M3 DSO138 Oscilloscope Kit - Pre Soldered. ₹ 1,588.98 (Excl. of GST 18%) GST Credit of ₹ 286.02 available. Know More. Status: Only 5 left in stock. Mini Oscilloscope. Max Input Voltage: 50V Peak (1x Probe) Max RealTime Sample Rate: 1 Msps. Analog Bandwidth: 0 ~ 200 Khz. The dso138 oscilloscope case kit. The kit contains everything you need to construct the case enclosure for your DSO 138 oscilloscope. The first thing you need to do is peel off the brown protective paper from the perspex panels. you may find a few remaining bits of squares that haven't been removed, take them all out before you start assembling Unofficial DSO150 User Manual by Daniel F F Ford, Australia [Draft 0.1, 4 March 2018] Display and Controls Connections Attention: 1. Power supply voltage must not exceed 10 V, otherwise it might damage the ICs inside. 2. Allowed maximum signal input voltage is ±50 Vpk with any 1× probe (including the supplied clip probe). Power Supply: Connect a Step 2: Tools. DSO to USB TTL connections: GND to GND. TX to TX. RX to RX. If it doesn't work, reverse the connection with the TX and RX pins. Staying like this: DSO to USB TTL connections: GND to GND. All parts required for completion are included, along with assembly instructions and a user manual ; The scope can run on USB or a single cell 3.7V Li-ion battery ; The overall size of DSO138mini is only 2/3 of DSO138, so it is much more suitable for hand-held operation DSO138 Oscilloscope, DSO 138 DIY Mini Oscilloscope, 2.4" TFT 1MSPS Build manual for the DSO138 acrylic enclosure Carefully check the content auf the case-kit: • acrylic parts: base-plate, 3 intermediate plates, cover-plate, 4 side-parts • red acrylic parts: 3 slide-switch caps, 5 pushbutton-caps (+1 or 2 spares) • 4 long bolts M3x30, 8 nuts M3, 4 cover-nuts M3 • 4 short M2x6 bolts, 4 M2 nuts The fact that you can buy it probe for just a few extra 3€ to 4€ or about $5 is nice, since you will have for that price the probe and also the aligator to bnc cable, since the second one is already included. The FNIRSI DSO-138 PRO oscilloscope specs are bellow: Display. 2.4″ TFT (320×240) Bandwidth. 200Khz. the page describes a daughter board and alternative firmware to add another channel to the DSO138. I have a standard DSO138, but the power supply is 9v, so a little awkward and a bit larger for transforming into a module. I am not yet sure whether this daughter board would also be compatible with the DSO138mini (which runs off 5v). The serial port of DSO138 (J5) contains three pins, TXD, RXD, and GND. TXD is an output pin (out of DSO138) and RXD is a input pin (into DSO138). GND is the common reference. Please make sure they are connected correctly if you use different Uart-USB converter. 4. Upgrading Steps 1) Close the jumpers JP1 and JP2 (see Fig. 4) on the bottom Step 1: Reading and Changing the Oscilloscope Display. Every oscilloscope has a window that displays the voltage output of your signal. In every display, the y-axis is voltage, and the x-axis is time. You can zoom in and out of the display grid by adjusting the "Volts per division"* or "Seconds per division".
