1730–Series Operating Instructions
2–4
9 MAG
Toggles between on and off. Operates in conjunction with the SWEEP mode to
provide usable sweep rates as follows:
2LINE + MAG = 1 ms/div
2FLD + MAG = 1 full vertical interval
1LINE + MAG = 0.2 ms/div
The vertical interval displayed in 2FLD MAG is the one following the selected
field trigger; for example, if FLD 1 is selected as the trigger, the vertical interval
displayed is the one between field 1 and field 2 (field 2 interval).
10 FIELD
Toggles between FLD 1 and FLD 2. The ALL mode is accessed, in the LINE
SELECT mode, by holding the FIELD push button in until the word ALL
appears on the CRT readout for 2LINE or 1LINE sweep or a bright–up strobe
appears in both fields for 2FLD sweep.
This switch determines which field triggers the 2FLD sweep. The selected field
trigger is the first (left) field displayed. For example, selecting Field 2 trigger
places field 2 on the left, followed by field 1.
In LINE SELECT, the indicator lights go off but triggering of the 2FLD sweep
continues on the selected field. A line strobe identifies the selected line. In
1LINE or 2LINE sweep, the FIELD button determines the field from which the
selected line is displayed (field 1, field 2, or ALL fields). When exiting ALL
fields display, switching defaults to FLD 1.
11 POSITION
Variable control that positions the waveform display horizontally.
12 FOCUS

13 SCALE
