If Ref Out; If Test Out; 2/ 3/ 4 (Integrated Connector); Source In - Keysight Technologies PNA Series Installation Manual

System Description
N5292A Test Controller Description

IF Ref Out

IF reference output connection provides direct access to the IF signal from the
module and is accessed by changing a switch setting in the millimeter wave
dialog. This enables you to connect and to measure higher frequency IF output
signals.

IF Test Out

IF test output connection provides direct access to the IF signal from the
module and is accessed by changing a switch setting in the millimeter wave
dialog. This enables you to connect and to measure higher frequency IF output
signals.

1 / 2/ 3/ 4 (Integrated Connector)

Provides an integrated interface for the RF, LO, and IF signals to and from the
millimeter wave modules.
Ports 3 and 4 features are not present on the N5292A with Option 200.
Refer to

Source In

Receives amplified RF signal to the millimeter-wave module's RF Input.
Connects from the PNA's – SOURCE OUT to the corresponding N5292A Source
In. This enables each port to have independent RF port power levels on all to
4-ports (if available).

Low Band

Receives an amplified LFE signal (900 Hz to 100 MHz) from the PNA's 1/2/3/4
ports that is combined with the main source signal in the test set and sent to
the integrated connector. Requires PNA/PNA-X with Option 225 or 425.

On/Standby Power Switch

LED is green when the power is on and amber when in standby mode.

Active LED

When the test set is connected and addressed by a analyzer, the LED is On
(illuminated). The LED is Off (not illuminated) when the test set is in Standby,
or not addressed by the analyzer.
