hp1725a

This is a HP 1725A oscilloscope. This dual channel laboratory oscilloscope has an input voltage range of 10mV/div to 5 V/div vertical deflection. The scope is capable of providing CH A, CH B, ALT, CHOP, A+B, and A vs. B display modes as well as a 10 nS sweep rate expandable to 1 nS/div. It also has selectable impedance of 50 ohms to 1 Megohm input.

This unit comes with a operations and service manual (see pictures).

Testing: I have been able to test at least some functions of the scope, with my wavetek 3001 signal generator. It works fine at the 275 MHZ input frequency (see first pictures). The amplitude on the screen corresponds to the wavetek amplitude. Both channels work as well as the trigger. I am sure that there are some functions of the scope that I did not test, therefore I am offering a :SATISFACTION: Serial Number 06834.
