3 VMA Mode
3.11 Phase and Amplitude vs Time Measurement
If the instrument is in Single sweep, and Averaging/Holding, and you want to take
one more sweep without resetting the Average trace or count, go to Meas Setup
and increment the average count by 1 by pressing the Step-Up key while
Average/Hold Num is the active function. You can also do this by sending
:CALC:AVER:TCON UP.
Restart
Restarts the current sweep, or measurement, or set of averaged/held sweeps or
measurements. If you are Paused, pressing Restart performs a Resume.
The front-panel key Restart performs exactly the same function.
The Restart function is accessed in several ways:
–
Pressing the Restart key
–
Sending :INIT:IMM
–
Sending :INIT:REST
See "More Information" on page 1833
Remote
Command
:INITiate[:IMMediate]
:INITiate:RESTart
Example
:INIT:IMM
:INIT:REST
Notes :INIT:REST and :INIT:IMM perform exactly the same function
Couplings Resets average/hold count k. For the first sweep overwrites all active (update = on) traces with new
current data. For application modes, it resets other parameters as required by the measurement
Status Bits/OPC
dependencies
This is an Overlapped command
The STATus:OPERation register bits 0 through 8 are cleared , except bit 6 (Waiting for Periodic
Sync). Initiating a measurement and Waiting for Periodic Sync could be asynchronous
The STATus:QUEStionable register bit 9 (INTegrity sum) is cleared
The SWEEPING bit is set
The MEASURING bit is set
Backwards
Compatibility
Notes
For Spectrum Analysis Mode in ESA and PSA, the Restart hardkey and the :INIT:REST command
restarted trace averages (displayed average count reset to 1) for a trace in Clear Write, but did not
restart Max Hold and Min Hold
In X-Series, the Restart hardkey and the :INIT:REST command restart not only Trace Average, but
MaxHold and MinHold traces as well
