Internal Second LO Generator (up to 26.5 GHz)
Option R&S
ZNA-B5
For a 4-port R&S
ZNA, hardware option R&S
ZNA-B5 provides a second LO that ena-
bles parallel measurement of a and b waves in frequency converting measurements.
This option is not available for 2-port R&S
ZNA.

Memory Extension for Data Streaming
R&S
ZNA-B7
Hardware option R&S
ZNA-B7 comprises an additional memory board, that is exclu-
sively used for buffering data of the measurement and reference receivers. Compared
to the standard memory, the buffering speed is twice as high.
This high-speed memory is particularly useful for
, because a
high time resolution requires a high IF bandwidth and hence a large amount of data to
be buffered. The "Pulse Profile" sweep type uses the R&S
ZNA-B7, if available.
The doubled memory speed also doubles the number of wave quantities that can be
measured simultaneously at a given bandwidth. The following table presents optimum
values.

The number of wave quantities that are required to measure a certain quantity,
depends on the setup and the calibration. E.g., a calibrated gain measurement with
"One Path Two Ports" calibration requires the simultaneous measurement of three
wave quantities.
