is designed for simplicity, featuring a logically grouped front panel and a clear 7-inch TFT color display. It offers a and a 1GSa/s real-time sampling rate , making it more than capable of handling common electronic debugging tasks. 1. Safety First
: Always calibrate your probes before use. Connect the probe to the BNC input and the built-in compensation pin (usually 1kHz square wave) and adjust the probe's trimmer capacitor until the waveform is perfectly square.
The is a popular entry-level digital oscilloscope, well-regarded by hobbyists, students, and electronics repair technicians for its affordability and compact “tablet” form factor. However, like many budget-friendly test instruments, the device often ships with a sparse quick-start guide or a CD containing the full manual.
Insert a FAT32-formatted USB flash drive into the front panel USB slot. Press the button. hanmatek dos1102 manual
Connect the probe alligator ground clip to the ground tab right next to it. Step 3: Set Software Attenuation Press the button on the front panel. Look at the onscreen menu and find the Probe option.
Choose your desired parameters, such as , Period , Peak-to-Peak (Vpp) , or RMS Voltage .
: 1 GSa/s (single channel) or 500 MSa/s (dual channel). Display : 7-inch TFT color LCD, 800 x 480 pixel resolution. Vertical Sensitivity : 5 mV/div to 5 V/div. Time Base Range : 2 ns/div to 1000 s/div. is designed for simplicity, featuring a logically grouped
While the button is incredibly convenient for beginners—automatically adjusting the vertical scale, horizontal scale, and trigger settings to display an active signal—relying on it exclusively limits your troubleshooting capabilities. Making Manual Adjustments
The DOS1102 balances performance with a slim form factor, making it ideal for workspaces with limited desk space. : 110 MHz.
Noise on the signal confusing the trigger. Manual reference: Trigger Coupling and Noise Rejection. Fix: In the Trigger Menu, change Coupling to HF Reject (high-frequency reject). This filters out sharp noise spikes. Alternatively, increase the Trigger Holdoff time—this tells the scope to ignore triggers for a short period after each trigger event. Safety First : Always calibrate your probes before use
You can access the official on the Manuals+ website , which includes details on setup, operation, and troubleshooting.
The most critical knob. Adjust it to sit within the waveform's vertical span to achieve a stable display.
Toggle the menu key until it matches your physical probe setting: . Note: If these do not match, your voltage readings will be off by a factor of 10. Step 4: Perform Probe Compensation
