Applicable Models: Multi-port systems with > 4 ports (Read-Write) Maps the physical VNA ports to a device of balanced and single-ended logical ports for multi-port systems with greater than 4 ports. The device type is selected using CALCulate:FSIMulator:BALun:DEVice. See Also: CALC:FSIM:BAL:PAR:CAT? - returns the list of measurement parameters available for the currently selected topology. CALC:FSIM:BAL:PAR:CUST:DEFine and CALC:MEAS:PAR - defines measurement parameter corresponding to a custom topology for systems where the port count is expandable beyond 4 ports. |

Parameters |
|
<cnum> |
Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1. |
<device> |
(String) Device type for the balanced measurement. ‘B’ means the Balanced port; ‘S’ means the Single-ended port. Choose from: B – 1 port balanced device (2 ports) BB – Balanced - Balanced device (4 ports) BS – Balanced - Single-ended device (3 ports) BSS – Balanced - Single-ended - Single-ended device (3 ports) SB – Single-ended - Balanced device (3 ports) SSB – Single-ended - Single-ended - Balanced device (4 ports) |
<topology> |
(Int array) Physical port numbers mapped to the logical ports, separated by ‘,’. ‘B’ (Balanced) requires 2 physical port numbers: <nPos>, <nNeg>. ‘S’ (Single-ended) requires 1 physical port number. |
