Winn BRAVO Great scope....
Check the SN, get servie manual and see the notes on A5 SMD cap leakage and NVRAM battery and replacement.
the PROBE CMP of 2465B is proportional to the sweep rate.
Different from all other scopes with a 1 kHz. COMP
As the output is not intended for a perfect sq wave at high freq, use it for:
1/ Probe comp AT 1 KHZ: Set 1 Ms..100 uS /div, comp orobe
2/ Use for SWP cal check at at all rates.
See manual for sch of COMP ckt , use of the COPM out.
The common probes like P6137 for COMP method, notice comp is always done at 1 kHz not HF
