the RX Tone with FED test using multiple frequencies,
by configuring the following parameters:
Current Group is the current test group name, for

Here you can switch to another Frequency test

Termination Resistance defines how much resistance the tester uses
to connect to the line, and is set as follows:
for VF Receive Tone, a read-only value of 600 Ω.
for WB Receive Tone, select 100, 120, or 135 Ω.
