8.2.1

 

Path-independent remote control programs

The default directory for R&S

 

ZND user data is

C:\Users\Public\Documents\Rohde-Schwarz\Vna

. Other instruments may use

different default directories. To make remote control programs compatible, it is recom-
mended to define all paths relative to the default directory, to be set via

MMEMory:CDIRectory DEFault

.

// Select default directory, change to sub-directory (relative to default directory)

MMEMory:CDIRectory   DEFault 
MMEMory:CDIRectory   'Traces'

MMEMory:STORe:TRACe 'Trc1', 'S21.s1p'
MMEMory:LOAD:TRACe 'Trc1', 'S21.s1p'

// Alternative, more compact definition

MMEMory:CDIRectory   DEFault 
MMEMory:STORe:TRACe 'Trc1', 'Traces\S21.s1p'

You may also read the default path (

MMEMory:CDIRectory?

) and use the external

RC program to build the complete paths.

8.2.2

 

Trace and diagram handling

The following sections provide examples for efficient channel and trace definition and
convenient diagram handling.

8.2.2.1

 

Assigning channels, traces, and diagrams

The following example is a short version of 

Chapter 8.1.2, "Channel, trace and diagram

handling"

, 

on page 1146.

// Reset the analyzer

*RST
