Using your Attenuator as a Variable Back Reflector

Setting Up the Software

To start setting up the Back Reflector application

1. Press B

ACK

EFL

After pressing this the first parameter (

INS LOSS

) is ready to for

editing.

2. Edit the value insertion loss with the Modify keys.

3. Press B

ACK

EFL

4. Edit the value reference return loss with the Modify keys.

Figure 4-2

Editing the Value for the Reference Return Loss

5. Press B

ACK

EFL

6. Edit the value attenuator return loss with the Modify keys.

See “Using the Modify Keys” on page 29 for information on
editing with the Modify keys.

Resetting the Parameters

To reset any of the back reflector parameters, press and hold B

ACK

EFL

until the value resets (this takes approximately two seconds).

INS LOSS

resets to 2.000dB.

RL REF

resets to 14.700dB (the return loss for the glass/air

interface at an open connector)

RL INPUT

resets to 60.000dB.

Executing the Back Reflector Application

If you have just set up the application, then you only need to press
E

XEC

to run the application.
