Troubleshooting

The table below lists possible errors and remedies.

Error

Possible cause

Remedy

No output signal, LED next to the
mains switch on the rear of the
converter panel off.

Converter not power-supplied

Check power supply and fuse
(see

Chapter 2.3.3, "Fuse

Power control fails, frequency
converter operates at maximum
output power.

Control connection not estab-
lished

Check connecting cable and port
assignment of control connectors.

Inaccurate converter source lev-
els

Insufficient settling time, espe-
cially for fast sweep and strong
power variations

Increase sweep time ("Channel >
Sweep > Sweep Time")

Inaccurate converter source lev-
els, even at reduced speed

Power coefficients entered and
converters do not match, e.g. the
coefficients of port 1 and port 2
are interchanged

Make sure that all coefficients are
correct and assigned to the right
analyzer ports (see

"Entering Power Coefficients"

Additional Information

For a comprehensive description of the frequency converter mode including remote
control refer to the R&S ZVA/ZVT online help system or to the printable operating man-
ual, which is available for download at

.

Application notes related to the frequency converter are also available for download,
see

http://www.rohde-schwarz.com/product/zva-z

The text book "Fundamentals of Vector Network Analysis" by Michael Hiebel is an ideal
complement for the information given in the user documentation. The book combines
theoretical background and practical measurements on an R&S ZVA network analyzer.
In case of interest please contact your local R&S office.
