Cursor Knob Allocation Menu 1
If MEAS Is selected from this menu, the Voltmeter measurement Is
performed on an area of the A sweep that Is Intensified by the B sweep
display. The Voltmeter measurement is, In effect, gated by the B sweep,
with the gating Interval starting approximately at B sweep start + (0.5
division + 20 ns) and ending approximately 11 divisions from B sweep start.
If measurement tracking cursors are enabled, they will track with the B
sweep display. The - OR DELAY knob will control the B delayed sweep
position, even though the DELAY time Is not displayed. When a Volts
measurement Is selected when B Trigger MODE Is not RUNS AFTER, an
error message “USE RUNS-AFTER-DELAY TRIG MODE" will be displayed,
and the Volts measurement will not start up. If B Trigger MODE is changed
while a Volts measurement is running, the Voltmeter measurement is
canceled, without a message, and the DELAY measurement runs.
If DELAY Is selected, the |- OR DELAY knob will control the B delayed
sweep position, and the DELAY measurement runs, displaying the delay
tlme value In the top line of the readout.
If horizontal mode Is changed to A when the above menu Is displayed, the
menu will disappear, but the selected Volts measurement will continue run-
ning, with the measurement tracking cursors tracking the A sweep (as In
the normal, nongated version of the Volts measurement) .
