INSTrument:NSELect <Channel>
Selects a channel as the active channel.
Parameters:
<Channel> Number of the channel to be activated. The channel must be
created before using CONFigure:CHANnel<Ch>[:STATe] ON.
Range: 1, 2, ...
*RST: 1
Example:
CONF:CHAN2:STAT ON; :INST:NSEL?
Create channel no. 2 and select it as the active channel. The
query returns 2.
INSTrument:PORT:COUNt?
Returns the number of test ports (Port 1, Port 2 ...) of the analyzer.
Example:
INST:PORT:COUN?
Return the number of ports of your analyzer.
Usage: Query only
INSTrument:SMATrix <Boolean>
In "set direction" this command perfoms a default setup or "clear" of the switch matrix
RF connections; in "get direction" it queries whether at least one RF connection to a
switch matrix is configured.
Parameters:
<Boolean> ON | 1 (setting) – adds all registered switch matrices to the RF
configuration, performing a default assignment of VNA ports and
test ports.
OFF | 0 (setting) – removes all switch matrices from the RF con-
figuration
1 (query) – at least one RF connection to a switch matrix
0 (query) – no RF connection to a switch matrix
Example: See SYSTem:COMMunicate:RDEVice:SMATrix:
CONFigure:STARt
INSTrument:TPORt:COUNt?
Returns the total number of test ports.
In absence of switch matrices, i.e. if no RF connection to a switch matrix is configured,
this is identical to the number of VNA ports (see INSTrument:PORT:COUNt?).
