(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

SYSTem:ABORt:THReshold?

Default

0 - No threshold time; all sweeps are immediately aborted.

(Read-only) Returns the number of the active channel. The active channel is the channel number that contains the active measurement. The active measurement is the trace that has a highlighted Tr# in the Trace Status area.

Remote operation returns immediately after the dialog is launched. This is done to avoid timeout issues with I/O protocols such as VISA. Although it is possible to send commands to the VNA while the dialog is open, this is not encouraged. Application programs should wait until the dialog is closed before resuming remote operations.

Parameters

(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.

See list of all SCPI Errors.
