I have a used, military surplus Hewlett Packard Model 1720a Oscilloscope in good working condition for sale.
Specs off the internet:
The 1720A Oscilloscope is a precise, wide band (dc to 275MHz), high
performance oscilloscope featuring vertical deflection factors of 10 mV/div
to 5v/div with 2% attenuator accuracy.
Vertical functions that can be selected are channel A, channel
B, A+B or A-B. Input coupling can be AC, DC, 50-ohms, or
ground. Channel B may be inverted. It has a switch-selectable
50-ohms or 1 Mohm input with full bandwidth in either mode.
The main time base is calibrated from 10 ns/div to 5s/div in 24
ranges. The magnifier expands all sweeps by a factor of 10 thus
extending fastest sweep to 1 ns/div. The delayed time base has
calibrated ranges from 10 ns/div to 20 ms/div in 20 steps.
Delayed sweep automatically starts at end of delay period.
Internal triggering is stable in excess of 275MHz and requires
only 1 cm of vertical deflection and is selectable from channel
A, channel B, or composite. Trigger coupling can be AC, DC, LF
REJ, or HF REJ. Has a bright 6 X 10 div. internal graticule CRT
with post acceleration 20.5 kV potential. Also has a 1kHz
internal square wave calibrator.
---------
Probe and leads are included. I have fired it up and it works fine. case
has a handle and a latch on cover. 2 of the rubber feet on the case
are missing, but no other obvious defects.
I am looking for 175 bucks locally in RI, will drive and meet halfway
for an Eastern MA or Eastern CT sale.
I can take a sale shipped CONUS, keep in mind this bad boy
weighs in at around 35 pounds before packing, so 175 + the freight.
I have some pics I can email, they are a bit too big to post here.
