VNA Master™Programming Manual : All Mode Commands : :INSTrument Subsystem
 
:INSTrument Subsystem
One instrument may contain many logical instruments (“modes”). This subsystem controls the selection of the current instrument mode.
 
Query Available Modes
:INSTrument:CATalog:FULL?
Description
Returns a comma‑separated list of available modes. Mode names are enclosed in double quotes (“ ”). The application number immediately follows the string name. For example: “HI_PM”10,”MWVNA”26
Syntax:
:INSTrument:CATalog:FULL?
Cmd Parameter
NA (query only)
Query Response
NA (comma separated list)
Front Panel Access
Shift‑9 (Mode)
 
Select Mode by Number
:INSTrument:NSELect
Description
Sets the instrument mode based on the value of <integer>. The query version returns the number that is associated with the current mode. Use :INSTrument:CATalog:FULL? to get a list of available mode names and their integer representations.
Syntax
:INSTrument:NSELect <integer>
:INSTrument:NSELect?
Cmd Parameter
<NR1> (integer)
1 = SPA (Spectrum Analyzer mode)
10 = HI_PM (High Accuracy Power Meter mode, Option 19)
14 = IA (Interference Analysis, Option 25)
15 = CS (Channel Scanner, Option 27)
26 = MWVNA (Vector Network Analyzer mode)
30 = AMFMPM (AM/FM/PM mode, Option 509)
102 = VVM (Vector Voltmeter mode, Option 15)
Query Response
<NR1> (integer)
1 = SPA (Spectrum Analyzer mode)
10 = HI_PM (High Accuracy Power Meter mode, Option 19)
14 = IA (Interference Analysis, Option 25)
15 = CS (Channel Scanner, Option 27)
26 = MWVNA (Vector Network Analyzer mode)
30 = AMFMPM (AM/FM/PM mode, Option 509)
102 = VVM (Vector Voltmeter mode, Option 15)

:INSTrument:CATalog:FULL?
:INSTrument[:SELect]
Front Panel Access
Shift‑9 (Mode)
Note 
Switching modes can take longer than 60 seconds, depending on the application. Anritsu Company advises you to set the remote PC time‑out to 120 seconds in order to avoid unexpected time‑out errors.
 
Select Mode by Name
:INSTrument[:SELect]
Description
Sets the instrument mode based on the mode name that is specified by <string>. The query version returns the name of the current mode. Use :INSTrument:CATalog:FULL? to get a list of available modes. For example, for Vector Voltmeter, use “VVM”.

AMFMPM = AM/FM/PM mode
CS = Channel Scanner
IA = Interference Analysis
HI_PM = High Accuracy Power Meter
MWVNA = Vector Network Analyzer
SPA = Spectrum Analyzer
VVM = Vector Voltmeter
Query Response
<string> HI_PM|MWVNA|Power Monitor|VVM
AMFMPM = AM/FM/PM mode
CS = Channel Scanner
IA = Interference Analysis
HI_PM = High Accuracy Power Meter
MWVNA = Vector Network Analyzer
