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
µsec to 2.5 µsec, 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.
