The fast edge low-aberration. This means a 1ns or better edge with good settling at the transition, no ringing or other issues this is usually a cal source or a tunnel diode pulser to speed up the edge time. If you are located close, I could use some 2xxx content and have all the cal gear needed. Being 300 Mhz when you get to the high frequency compensation section this most likely going to need TD signals or type 284 edges. TD pulsers will need high amplitude squairwaves. Mine needs about 70ish Vpk-pk for the TD to start doing its thing.

Where are you located? Maybe someone close has the cal generator.

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?-- This email has been checked for viruses by Avast antivirus software. |
