Measuring Insertion Loss for Power Meter (Option 600

Measuring Insertion Loss for Power Meter (Option 600 - Power Meter Only)

NOTE: This measurement is only available if you have Option 600 - Power Meter, and requires an 8482A/8481A power sensor.

Before making a power measurement, you need to store a PM Loss value that will compensate for the loss of the devices you use to connect to the transmitter.

Step
Notes

1
Connect the cable or device.
Connect the high power attenuator and remaining 60 cm (2 ft) cable (not the cable used for normalization) between the two 10 dB pads that were used for normalization.

2
[Level/Location]
If the insertion loss trace is not visible, you can change the reference level or use Autoscale to have the test set select a reference level for you.

Press [Autoscale] to display the trace so that it fills the screen from top to bottom.
Press [Ref Level] and then enter the appropriate value and press [dB] to manually select a level for the trace.
Press [Scale/Div] and then enter the appropriate value and press [dB] to manually select the number of dBs per line on the graticule.

3
[Store As]

4
[Store As PM Loss]
Saves the loss for use with the power measurement. This PM Loss figure only remains valid for as long as you continue to use the same "characterized assembly", that is, the same cables and pads.
If Option 600 - Power Meter is not installed, [Store as PM Loss] and [PM Loss] are unavailable.
