I'm trying to calibrate my 2465 but don't have the Tektronix calibration equipment. For the CAL 01 Horizontal adjustments, I used square waves from my Hantek oscilloscope/multimeter/waveform generator, which only goes up to 10MHz square waves. I think this was not great but was adequate for these calibrations. However, when I progressed to the vertical calibrations, I'm not even sure what was required. When it says to connect a 0.5 V, standard-amplitude signal from the Calibration Generator, what does that mean? The service manual says that the Calibration Generator is "Fast-rise, low-abberation amplitudes: to 1V. Rise time: 1ns or less. Repetition rate: 1 kHz to 100 kHz. Precision amplitudes: 0.01 V to 50 V +/-0.25%." Okay, so when they say a 0.5V standard-amplitude, what frequency do they want? Is that 0.5V peak-to-peak? Is it AC (goes positive and negative) or DC (all positive)? Do they want a square wave, or do they want a constant DC voltage?
