2.2.3 Master USB Connectors
Two type A USB connectors (master USB), equivalent to the master USB connectors on
the front panel; see
chapter 2.1.2, "USB Connectors" , on page 7.
2.2.4 FILTER CONTROL IN
For future extensions.
2.2.5 PORT 1 / 2 / 3 SOURCE
Three pairs of 2.92 mm connectors used to loop external components, e.g. amplifiers,
into the source signal paths of test ports 1, 2, and 3. The source signal path of test port
2 does not contain any additional modules; see
figure 3-2 .
RF emissions
To comply with the emission requirements, always use semirigid cables (preferably, the
cables supplied with the extension unit) to connect external components or close the
OUT/IN loops.
2.2.6 CASCADE IN
Input connector for pulse generator signals from the R&S ZVA24 network analyzer (with
option R&S ZVA-K27). The two pulse generator signals control the pulse modulators in
the extension unit (options R&S ZVAX-B271, R&S ZVAX-B272, R&S ZVAX-B273). Refer
to the detailed description of the pulse generator in the help system of your network
analyzer.
The pulse modulators are controlled either via the CASCADE IN or via the EXT PULSE
GENERATOR IN connectors; see
figure 3-3 on page 24 . The pulse generator signals
are also fed to the PULSE GENERATOR OUT connectors. See chapter 2.2.7, "EXT
PULSE GENERATOR IN / OUT" , on page 15.
