SZU100A

Manual 1425.3061.02 ─ 04

The R&S

SMW adjusts the internal calibration routines to the R&S

SZU.

"Adjust All" is disabled, i.e. in this configuration, you cannot execute adjust-
ment routines for the R&S

SMW.

8. Select "Adjust External Frequency Converter A/B" for all R&S

SZU.

The R&S

SMW automatically calibrates the parameters of the externally con-

nected R&S

SZU.

9. When completed, check that no errors occurred.

If the internal adjustments detect any errors, see User Manual of R&S

SMW,

chapter Internal Adjustment Settings for further information on how to pro-
ceed.

Behavior of the R&S

SMW When Working with

the R&S

SZU

At startup, the R&S

SMW firmware takes control of the R&S

SZU almost entirely.

You can only select the analog I/Q connection (differential or single ended), provi-
ded you are working with only one R&S

SZU.
