3.9 VSWR Compound (VSWR: VS, VSA)
3.9.1 General
CO3000 Display shows: VSWRn
with n = the number of the VSWR, starting with 1 (e.g. VSWR1 or VSWR2)
A VSWR compound is comprised of two devices:
VSn = X-Axis (Device type: 0x4044)
VSAn = Azimuth (Device type: 0x0451)
All values are transmitted in CM (centimeter) or DG (degrees).
Negative values are not possible for CM.

Command Return Value Description
LD x DV x Load X-Axis, numerical addressing
Valid values for x: 2, 6, 10
LD a DV a Load Azimuth-Axis, numerical addressing
Valid values for a: 6, 10, 14
LD VSn DV x Load X-Axis of VSWRn
Valid values for n: 1, 2, 3, …
LD VSAn DV a Load Azimuth-Axis of VSWRn
Valid values for n: 1, 2, 3, …
Return value of *OPT? command deterimnes values for x and a
(Position of return value, starting with 0).
Example of return value for *OPT? command:
0,0,VS1,0,0,0,VSA1,0,0,0,VS2,0,0,0,VSA2,0
Here x=2 for VS1, a=6 for VSA1, x=10 for VS2, a=14 for VSA2
