3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
:WAV:IF:FREQ?
Couplings A change in Span, Digital IF BW or IF Path parameters can result in a change of the IF Frequency value
3.1.9 Sweep
Accesses controls to configure and control the acquisition of data, and the X-axis
parameters of the instrument.
Depending on the selected mode and measurement, these controls might include:
Sweep Time, Continuous/Single, Pause/Resume, X Scale and Number of Points.
3.1.9.1 Sweep/Control
Accesses controls that let you operate the sweep and control functions of the
instrument, such as Sweep Time and Continuous/Single.
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 269
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
