Frequently Asked Questions - 1265 PeakTech
How to perform probe compensation?
Set the probe attenuation to 10X in the menu and on the probe switch. Connect the probe to channel 1, then the probe tip and ground to the probe compensator. Press AUTOSET. Adjust the compensation screw on the probe until a perfect square wave is obtained (neither overcompensated nor undercompensated).
How to perform automatic calibration?
Disconnect all probes and cables from the inputs. Press UTILITY, then H1 for the FUNCTION menu, turn the M knob to select 'Adjust', then press H2 for 'Self Cal'. Confirm to start calibration. Perform it if the ambient temperature changes by more than 5°C.
How to measure the frequency of a signal?
Press Measure to access automatic measurements. Select Freq from the menu. The frequency will be displayed at the bottom of the screen. You can also use cursors to measure the period and calculate the frequency (F = 1/T).
How to use the FFT function?
Press Math, then select FFT. Choose the source (CH1 or CH2) with F1, the window (Rectangle, Hamming, Hanning, Blackman) with the M knob, the format (dB or Vrms) with F3 and zoom with F4. The FFT waveform is displayed in green.
How to capture a single shot signal?
Set the trigger to Single mode in the Trigger menu. Select the trigger type (Edge for example). Set the trigger level with the TRIG LEVEL knob. Press RUN/STOP to arm the device. When the signal reaches the level, the oscilloscope captures the waveform and stops.
How to reduce noise in the waveform?
Use the Average acquisition mode. Press Acquire, then H1 for mode, select Average with F3 and set the number of averages with the M knob. This reduces random noise and allows you to see signal details.
How to take a measurement with cursors?
Press CURSOR to activate cursor mode. Use the function keys to select the type (voltage or time). Move the cursors with the M knob or arrow keys. The measured values are displayed in a window on the screen.
The oscilloscope displays nothing after power-on, what to do?
Check that the power cord is properly connected and that the switch is in the '-' position. Check the fuse next to the mains socket (2 AT, 250 V). If the fuse is blown, replace it with an identical model. If the problem persists, contact your dealer.
How to clean the oscilloscope?
Disconnect the device. Use a soft, damp cloth (well wrung) with a mild detergent if necessary. Do not use abrasive products or solvents. Avoid liquid entering the interior. Dry completely before reconnecting power.
How to save a waveform?
Press Save/Recall to access the save menu. Select Save Waveform. Choose a location (1 to 15) and confirm. You can also save to a USB stick via the USB host port.

The red line represents a square wave with amplitude in dB, the yellow line represents a square wave with amplitude in V, and the orange line represents an orange scale (ON/OFF) for the mode of the wave axis (Mode). The wave axis is labeled as 'OFF'. The x-axis is labeled 'Time' and the y-axis is labeled 'Value'. The data is measured at three different times (in seconds) and scaled by a factor of approximately four times (in dB).Gain (db) = 20Xlog (gain)
