3.11.1 Measure Menu.

The Measure menu contains items that control the taking of measurements.

Main Menu>Measure> Select Run/Stop Capture

Stop Stop data capture.

INITiate:CONTinuous OFF

Run Restart Data Capture.

INITiate[:IMMediate[:ALL] or INITiate:CONTinuous ON

SnglSweep Perform Single Sweep. For time span (TSPAN) settings from 2 µsec to 50µsec, the

single trace will be made up of 125 pixels at 1 sample/pixel. For TSPAN settings

from 5 sec to 5 µsec, the 125 trace pixels will each be the average of 2 or more

samples.

1) With INITiate:CONTinuous OFF, and TRIGger:SOURce BUS trig-

ger a single measurement with *TRG or {GET}.

2) With INITiate:CONTinuous OFF, and TRIGger:SOURce

BUS>SNSR1 arm for a single measurement with *TRG or {GET}. When

the sensor signal trigger qualifiers are met, a single trace measurement

will be made.

NOTE

For TSPAN settings from 20

sec to 2.5

sec, multiple triggers are needed to fill

all 125 pixels. For this reason, a triggered measurement with averaging set to

one is recommended if repetitive triggers are possible. This procedure will use

the minimum number of triggers to fill all 125 pixels.

Clr/Reset In the Stop mode clear all measurement results. This will cause all displayed

readings to be replaced by dashes. For GPIB operation this occurs when measure-

ments are initiated using the INITiate command. This guarantees fresh measure-

ment data rather than a re-read of previously read (stale) data. The measurement

status flag that precedes each GPIB query result also warns of stale data.

AutoSetup For the Pulse Mode automatically adjust the trigger and position controls to pro-

duce a waveform on the display. This does not override a channel set to OFF.
