ROUTe:RMODule:DRIVe:LIMit

Syntax

ROUTe:RMODule:DRIVe:LIMit {<max_drives>|MIN|MAX|DEF}, (@<rem_ch_list>)

ROUTe:RMODule:DRIVe:LIMit? [{MIN|MAX}, ] (@<rem_ch_list>)

Description

This command set the number of simultaneous coil drive activations to be allowed on the specified 34945EXT remote module connected to the 34945A Microwave Switch/Attenuator Driver. By specifying a value greater than one drive, you can improve cumulative switching times by allowing the 34945EXT to overlap channel drives.

Used With:

  • 34945A Microwave Switch/Attenuator Driver

Parameters

Name

Type

Range of Values

Default Value

<max_drives>

Numeric

Desired number of simultaneous coil drive activations allowed.

MIN = 1 drive, MAX = 8 drives

1 drive

<rem_ch_list>

Numeric

One or more 34945EXT remote module identifiers in the form (@sr00).

Select from s100 through s800.

This is a required parameter.

Remarks

  • Use discretion when specifying a value greater than one drive when configured for an INTernal (mainframe) drive source (see ROUTe:RMODule:DRIVe:SOURce[:IMMediate] command). The INTernal drive provides a very limited power source for driving channels, and driving multiple channels can cause the over-current protection circuitry on the 34945EXT remote module to be activated. An error will be generated and the operation will fail.  

  • The ROUTe:CHANnel:DRIVe:TIME:RECovery command sets the minimum recovery time for the drive power supply on specific channels. If you set the recovery time to any value greater than 0 seconds, the overlapping behavior of the ROUTe:RMODule:DRIVe:LIMit command may be temporarily suspended when those channels are operated.

  • If you reduce the number of simultaneous coil drive activations, the time required to complete a reset/preset will increase (also see ROUTe:CHANnel:DRIVe:PULSe:WIDTh command) and power supply recovery time (see ROUTe:CHANnel:DRIVe:TIME:RECovery command).

  • The drive setting is stored in non-volatile memory on the 34945EXT remote module.

Return Format

The query command returns the drive limit on the specified 34945EXT remote module. Multiple responses are separated by commas.

Examples

The following command sets a drive limit of five simultaneous coil drive activations on 34945EXT remote module #2 (slot 3).

ROUT:RMOD:DRIV:LIM 5,(@3200)

The following command returns the drive limit on 34945EXT remote module #2 (slot 3).

ROUT:RMOD:DRIV:LIM? (@3200)

Typical Response:  5
