R&S ESU Remote Control – Description of Commands

INITiate Subsystem

6.126 Operating Manual 1302.6163.12 - 03

In analyzer mode, this command continues a stopped measurement at the current position in single-

sweep mode. The function is useful especially for trace functions MAXHold, MINHold and AVERage if

the previous results are not to be cleared with Sweep Count > 0 or Average Count > 0 on restarting

the measurement (INIT:IMMediate resets the previous results on restarting the measurement).

The single-sweep mode is automatically switched on. Synchronization to the end of the indicated

number of measurements can then be performed with the command *OPC, *OPC? or *WAI. In the

continuous-sweep mode, synchronization to the sweep end is not possible since the overall

measurement "never" ends.

Example: "INIT2:CONT OFF"

'Switches to single-sweep mode.

"DISP:WIND:TRAC:MODE AVER

'Switches on trace averaging.

"SWE:COUN 20"

Setting the sweep counter to 20 sweeps.

"INIT2;*WAI"

'Starts the measurement and waits for the end of the 20 sweeps.

"INIT2:CONM;*WAI"

'Continues the measurement (next 20 sequences) and waits for the end.

Characteristics: *RST value: -

SCPI: device-specific

Mode: R, A

This command is an event and therefore has no *RST value and no query.

INITiate<1|2>[:IMMediate]

The command initiates a new sweep in the indicated measurement window.

In receiver mode with SINGLE SCAN selected, the R&S ESU performs a single scan and stops at the

end frequency. With CONTINUOUS SCAN selected, the scan is performed continuously until it is

deliberately stopped.

In analyzer mode, with Sweep Count > 0 or Average Count > 0, this means a restart of the indicated

number of measurements. With trace functions MAXHold, MINHold and AVERage, the previous

results are reset on restarting the measurement.

In single-sweep mode, synchronization to the end of the indicated number of measurements can be

achieved with the command *OPC, *OPC? or *WAI. In continuous-sweep mode, synchronization to

the sweep end is not possible since the overall measurement never ends.
