Applicable Models: All

(Read-Write) When a VNA setting is made while a sweep is in progress, the sweep is immediately aborted by default. This command allows you to change that behavior by specifying a time threshold. When a setting change is made during a sweep and if the total sweep time is less than the threshold time, then the sweep is allowed to finish instead of immediately aborting.

In general, VNA setting changes that could cause an aborted sweep are changes that affect how a measurement is made, such as changes in stimulus conditions.

For example, with a threshold setting of 60 seconds:

• Sweeps that require 60 seconds or less from start to finish will be allowed to complete if a VNA setting change is made at any time during the sweep.

• Sweeps that require MORE than 60 seconds from start to finish will be immediately aborted when a VNA setting change is made at any time during the sweep.

Notes:

• Preset clears this setting.

• Save state saves this setting.

• Sweep times are estimated.

• This setting affects ALL channels.

Parameters

<value>

Threshold time in seconds. Set to 0 to immediately abort a sweep when a VNA setting is made.

Examples

SYST:ABOR:THR 10

'When a setting is made during a sweep, if that sweep requires less than 10 seconds more to complete, it will be allowed to finish instead of aborting.

Query Syntax

(Read-Write) Sets and reads the state of channel coupling. This causes the VNA to emulate Keysight 8720 channel coupling.

When set to ON, all existing S-parameter channels receive the stimulus settings of the active channel. Subsequent changes made to any coupled channel are changed on all coupled channels.

Channels with applications such as SMC, VMC, GCA, Noise, IMD are not affected.

Coupling is primarily aimed at stimulus settings (such as start, stop, points, power) but also applies to many trigger settings and to Cal Set pointers.

(Write-only)  Sets up multiple channels for manual trigger and provides a method of triggering multiple channels using manual trigger. There are several prerequisites for using this command:

• Manual trigger mode must be used (INIT:CONT OFF)
• All channels in HOLD (SENS:SWE:MODE HOLD), not just the channels being triggered
• No acquisitions currently running (instrument is NOT sweeping - see ABORt:THReshold)
• All specified channels must exist

If the above conditions are not met, then the command will generate an error which describes what is at fault. If the above conditions are met, then the trigger count for the specified channels is set to 1. Issuing an *OPC? query will indicate when the first channel is armed (ready for manual trigger). It is not necessary to wait for *OPC? before sending INIT:IMM to trigger the first channel. After the first channel is triggered, *OPC? will indicate when all armed channels have finished acquiring data.

Channels will be sorted by channel number, and acquire in order from lowest channel number first to highest channel number last.

Parameters

<chanNums>

Existing comma separated list of channel numbers.

Choose from:

MAIN - Launches the Calibration Wizard which matches the current channel, such as standard S-params, NoiseFigure, GCA, and so forth.

CKIT - Launches the Version 2 Calibration Kit File Manager dialog box.

RESP - Launches the Response Cal Type Selection.

(Read-only) Returns the next error in the error queue. Each time the analyzer detects an error, it places a message in the error queue. When the SYSTEM:ERROR? query is sent, one message is moved from the error queue to the output queue so it can be read by the controller. Error messages are delivered to the output queue in the order they were received. The error queue is cleared when any of the following conditions occur:

• When the analyzer is switched ON.

• When the *CLS command is sent to the analyzer.

• When all of the errors are read.

If the error queue overflows, the last error is replaced with a "Queue Overflow" error. The oldest errors remain in the queue and the most recent error is discarded.
