S46/S46T/S46L Microwave Switch System Instruction Manual Section 3: Operation
:CONFigure:SPARameterN <string>
Define s-parameter string
Parameters <string> = ASCII string of up to 68 characters representing s-parameters enclosed
in single or double quotes (both quotes must be the same type).
Description This command allows you to store a string of up to 68 characters representing
s-parameters for channel
N
(
N
= 1 to 32 [
N
= 1 to 28 for S46L]). For example, the
following command stores s-parameters for channel 10:
:ROUT:CONF:SPAR10 "<s-parameters>"
Query This query returns the stored s-parameter string for channel
N
with no delimiters.
NOTE
For the S46L, the relay serial numbers are stored in
SPARameter1
through
SPARameter8
at the factory.
SPARameter1
through SPARameter4 correspond to
the SP6T relays in locations A through D, and
SPARameter5
through
SPARameter8
correspond to the SPDT relays.
If a relay is populated, the serial number will appear in the corresponding
SPARameter
. You can determine whether or not a relay is populated by using the
CONFigure:CPOLe
query.
If a relay is replaced or added after the S46L has left the factory, you must update
the serial number in the
SPARameter
location (if you want to maintain that
information).
STATus commands
A list of the
STATus
commands is contained in Table 3-8 .
STATus
commands are used to control
the status registers of the S46/S46T/S46L. Following the table are details defining the use of the
specific
STATus
subsystem commands.
NOTE See Status model later in this section for more details.
The
:STATus
command path is required to access all commands contained in the
:STATus
subsystem command set. To send any of the commands contained in the
:STATus
subsystem
command set, include the command path immediately before the command. For an example, see
the description of the specific command.
