SCPI Commands for the SurePatht Modules
VX4101A MultiPaq Instrument User Manual
3–275
[ROUTe:]SCAN:RATE <scan_rate>, <module_name>
<scan_rate> is either NORMal or FAST.
<module_name> is the module name assigned to the VX4330.
This command controls the maximum rate at which VX4330 channels in a scan
list can be sequenced. If a <scan_rate> of NORMal is specified in the
[ROUTe:]SCAN:RATE command, it takes approximately 16 ms plus the sum of
the close dwell and open dwell times assigned to the VX4330 and the trigger
delay time to:
open the VX4330 channel that is currently closed,
close the next VX4330 channel, and
pulse the front panel encode signal(s) corresponding to the closed channel.
The control signals applied to all relays on the VX4330 Module are verified after
the current channel is opened and after the next channel in the scan list is closed.
If a <scan_rate> of FAST is specified in the [ROUTe:]SCAN:RATE command, it
takes approximately 8 milliseconds plus the sum of the close dwell and open
dwell times assigned to the VX4330 and the trigger delay time to:
open the channel that is currently closed, and
to close the next channel in the scan list.
The VX4330 front panel encode signals are disabled and the relay control signals
are not verified after a channel is opened or closed.
NOTE. The SurePatht master on the VX4101A runs on a multitasking system.
The accuracy of the scan time varies depending on the load placed on the
VX4101A
Query Value
[ROUTe:]CLOSe?
<channel_list>
Indicates which relays are closed.
ROUTe:MODule:
CATalog:SUPPorted?
VX4320, VX4330, VX4350, VX4351, and VX4380
[ROUTe:]MODule[:DEFine]? The name of the module.
[ROUTe:]OPEN?
<channel list>
Indicates which relays are opened.
[ROUTe:]ID? List of the model numbers of the modules controlled by the
SurePath Master. The first model number returned is that of the
module that the Scanner Master is installed on. Subsequent
model numbers are those of modules in consecutive slots to
the right of the first module.
