Performance Tests
Performance Tests
The procedures in this section test the electrical performance of the PD1000A
Bias T Network using the specifications of Table 1 as performance standards.
Performance may be verified using either a vector or scalar network analyzer
setup. Errors due to directivity, source match, and return loss of the 'opposite
port' termination (and detector match in a scalar system) will add uncertainties
to your measurement. The most accurate method uses an error corrected
instrument. However, a scalar system will have acceptable results depending on
the quality of the components.
Record the results of the performance tests in
Return Loss of Input and Output Ports
The following instructions apply to both vector and scalar network analyzers.
Insertion Loss
Keysight PD1000A Bias T Operating Guide
1 Connect the equipment for a standard reflection measurement.
2 Calibrate the system with an open and a short.
3 Connect the appropriate RF port of the PD1000A Bias T Network to the
test port. Terminate the opposite port with a 50 Ω load.
The return loss of the terminating load should be at least 20 dB
better than the desired measurement value.
4 Measure the return loss. The specifications are listed in
Specifications"
on page 11.

2 Calibrate the system the system with a through line.
3 Replace the through line with the PD1000A Bias T Network.
