Agilent / HP 8516A
S-Parameter Test Set 45MHz to 40GHz
Description
The 8516A test set has a dual port architecture, which develops a separate reference channel for each incident port.
RF switching is done with a single built-in electronic switch.
For active device measurements, the test sets include the ability to apply DC bias (external) to the test port center conductors.
Also available are two 60 dB step attenuators, which allow control of the port 1 and port 2 signal levels.
The 8516A test set is coupler-based.
Two alternate coupler configurations are available.
The standard configuration is symmetrical and has identical dynamic range performance in both forward and reverse transmission measurements.
The port 1 step attenuator allows reduction of the port 1 output power for forward measurements, and the port 2 attenuator allows reduction of the port 2 output power for reverse measurements.
With the Option 003 configuration, the port 2 coupler is reversed.
For forward measurements, the port 2 signal is sampled directly through the main arm of the port 2 coupler.
Since coupling loss is removed, dynamic range is increased in the forward direction.
Since the port 2 step attenuator is inline with the port 2 sample, the power incident on port 2 may be reduced.
With Option 003, up to 1 W may be input into port 2.
Key Points
Frequency range: 45 MHz to 40 GHz
Attenuation range: 0 to 60 dB
Impedance: 50 ohm, nominal
DC bias: 500 mA, 40 Vdc maximum
Connector type: 2.4 mm (M)
8510B multiple test set configurations:
IF switching (Option 001 required in one of the test sets): The 20 MHz IF signal is daisy-chained from the test sets to the 8510
RF switching: The RF signal must be routed to the desired test set using a 33311C coaxial RF switch and a 11713A switch driver. The switch driver is controlled automatically by the 8510B over the 8510 system interface.
Options:
Option 001: Add IF switching
Option 002: Delete step attenuators and bias tees
Option 003: High forward dynamic range
