10 Monitor Spectrum Measurement

Single (Single Measurement/Sweep)

Single (Single Measurement/Sweep)
Sets the analyzer for Single measurement operation. The single/continuous state is Meas Global, so the
setting will affect all the measurements. If you are Paused, pressing Single does a Resume.

If you are already in single sweep, the INIT:CONT OFF command has no effect.
If you are already in Single Sweep, then pressing the Single key in the middle of a sweep does not restart
the sweep or sequence. Similarly, pressing the Single key does not restart the sweep or sequence if the
sweep is not in the idle state (for example, if you are taking a very slow sweep, or the analyzer is waiting for
a trigger). Instead, it results in a message. "Already in Single, press Restart to initiate a new sweep or
sequence". Even though pressing the Single key in the middle of a sweep does not restart the sweep,
sending INIT:IMMediate does reset it.
To take one more sweep without resetting the average count, increment the average count by 1, by
pressing the step up key while Average/Hold Number is the active function, or sending the remote
command CALC:AVER:TCON UP.

For Spectrum Analysis mode in ESA and PSA, the Single hardkey and the INITiate:IMM switched
from continuous measurement to single measurement and restarted sweeps and averages (displayed
average count reset to 1), but did not restart Max Hold and Min Hold. In the X-Series, the Single
hardkey and the INITiate:IMM command initiate a sweep/ measurement/ average sequence/hold
sequence including MaxHold and MinHold.
For Spectrum Analysis mode in ESA and PSA, the Single hardkey restarted the sweep regardless of
whether or not you were in an active sweep or sweep sequence. In the X-Series, Restart does this
but Single only restarts the sweep or sweep sequence if you are in the idle state.
INIT[:IMM] in ESA & PSA Spectrum Analysis Mode does an implied ABORt. In some other PSA Modes,
INIT[:IMM] is ignored if not in the idle state. . The X-Series follows the ESA/PSA SA Mode model,
which may cause some Modes to have compatibility problems.
