1730–Series Operating Instructions
2–3
3
CH–A–CH–B
Switch that toggles between Channel A and Channel B input. When held, the
1730–Series goes into an AB (BOTH) alternate mode, with the A input on the
left and the B input on the right in 2 Line or 2 Field (lines are overlayed in 1
Line sweep). When in the AB switching mode the REF is forced to EXT, the
FILTER is forced to LPASS, if it was in the LPASS–FLAT switching mode; if
not the FILTER remains in the previous position, and the DC REST goes to
SLOW. All three functions go back to their previous setting when the input is
switched out of AB. The DC Restorer can be changed after entering the AB
mode. When leaving (BOTH), the input always returns to CH–A.
4
GAIN (control)
Enabled when the GAIN switch is in VAR. Adjusts amplifier input gain rate to
make any input waveform signal, between 0.8 and 2.0 V peak–to–peak a
full–scale display. Control has no detent.
5
VERTICAL
Toggles between VAR, X5, and off. A BOTH mode consisting of VAR and X5
is accessed by holding the push button until both LED indicators are lit.
6
DC REST
Toggles the DC Restorer on and off. When turned on the restorer comes up as
previously selected, in either the SLOW or FAST position. Pushing and holding
the switch in toggles the restorer between FAST and SLOW. Once the restorer
speed has been selected, pushing the DC REST button turns the DC Restorer on,
at the selected speed, or off.
7
POSITION
Variable control that positions the waveform display vertically.
8
SWEEP
Toggles between 2LINE and 2FLD Sweep. 1LINE Sweep is accessed by
holding the SWEEP push button in until recognition occurs. The MAG is
automatically turned off if SWEEP is changed. Sweep rates are as follows:
2LINE unmagnified = 10
m
s/div
1LINE unmagnified = 5
