SENSe<cnum>:TDR:SPURious:AVOid:IMMediate

Applicable Models: All with TDR Options (S9x011A/B)

(Write-only) This command executes avoid spurious.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

Examples

Default

Not Applicable

SENSe<cnum>:TDR:SPURious:AVOid:STATe?

Applicable Models: All with TDR Options (S9x011A/B)

(Read-only) This command queries the avoid spurious state. This command is used only with Hot TDR mode.

  • This command is ON when :SENS:TDR:SPURious:AVOid:IMMediate command succeeds.

  • This command is OFF when :SENS:TDR:SPURious:AVOid:IMMediate command fails to find a spur.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

Examples

SENS:TDR:SPUR:AVO:STAT?
sense:tdr:spurious:avoid:state?

Return Type

Boolean

1 - ON

0 - OFF

SENSe<cnum>:TDR:SPURious:INPut:DRATe <value>

Applicable Models: All with TDR Options (S9x011A/B)

(Read-Write) This command sets the value of input bit rate for avoid spurious.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

<value>

Value of input bit rate in bits per second (bps). The range is 1.21E6 to 60.8E9.

Examples

SENS:TDR:SPUR:INP:DRAT 1.5E9
sense:tdr:spurious:input:drate 1.5e9

SENSe<cnum>:TDR:SPURious:STATe?

Applicable Models: All with TDR Options (S9x011A/B)

(Read-only) This command queries the Hot TDR mode status.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

Examples

SENS:TDR:SPUR:STAT?
sense:tdr:spurious:state?

Return Type

Boolean

1 - ON

0 - OFF

SENSe<cnum>:TDR:SWEep:AVERage <bool>

Applicable Models: All with TDR Options (S9x011A/B)

(Read-Write) This command sets the TDR averaging trigger state on/off. When averaging trigger is on, one trigger makes one averaging measurement. For example, if the averaging factor is set at 16, one trigger makes a measurement 16 times.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

<bool>

ON or 1 - Turns averaging trigger on.
OFF or 0 - Turns averaging trigger off.

Examples

SENS:TDR:SWE:AVER ON
sense:tdr:sweep:average on

Query Syntax

SENSe<cnum>:TDR:SWEep:AVERage?

Return Type

Boolean

Default

OFF

SENSe<cnum>:TDR:SWEep:MODE <enum> 

Applicable Models: All with TDR Options (S9x011A/B)

(Read-Write) This command sets trigger mode.

Parameters

 

<cnum>

Channel number of the measurement. If unspecified, <cnum> is set to 1.

<enum>

Trigger mode. Choose from:

HOLD - Trigger is on hold until the conditions are met, then the trigger event starts.

SINGle - Trigger event is run once.

RUN - Trigger event runs continuously.

Examples

SENS:TDR:SWE:MODE RUN
sense:tdr:sweep:mode run
