GOOD CONDITION - OPERATIONAL - GUARANTEED!
7 DAY RIGHT of RETURN for FULL REFUND if NOT 100% SATISFIED
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. subject to prior sale
