Front Panel Features
Standby Switch
This switch is used to place the internal DC power supply into Standby mode only. It is not an
AC line switch. The main power cord can be used to disconnect AC line power from the Test
Set.
Active LED
When the Test Set is connected and addressed by a PNA-X, the LED is ON (illuminated).
When the LED is OFF (not illuminated), the Test Set is in Standby, or not being addressed by
the PNA-X.
Note:
When two Test Sets are used, as in the 24-Port System, the first Test Set
connected to the PNA-X will never have an ON Active LED. Instead, the last Test Set will be
the Test Set showing the Active LED status for all.
•
If all of the odd numbered port LEDs are Off, PNA-X Port 1 is active and the Odd Test
Ports are terminated.
•
If all of the even numbered port LEDs are Off, PNA-X Port 2 is active and the Even Test
Ports are terminated.
Test Ports - 2.4 mm Bulkhead (male)
These ten ports are labeled Ports 3 to 12, and are the measurement ports for your DUT. The
bulkhead connector has a ruggedized hex nut that is 20 mm across the flats and is
compatible with Keysight torque wrenches.
Test Port Status LEDs
Each test port has an "S" and "R" status LED assigned to it. On the left side of the front panel
are the odd numbered port status LEDs, and on the right side are the even numbered port
status LEDs. The "S" indicates Source mode and "R" indicates Receiver mode for that test
port. An illuminated LED indicates that the port is active in either the Source (output) or
Receiver (input) path mode. In S-Parameter measurement mode S33, for example, both the
"S" and "R" status LEDs for Test Port 3 will be illuminated, since Port 3 is both outputting a
source signal and receiving a reflected measurement signal.
