mode is typically used for DDS, ISDN, HDSL, T1 and XDSL copper qualifications.
Measurements
Transmit & Receive
Receive frequency and level is displayed next to RX and is displayed in Hz and dBm.
To change the TX frequency, tap the up or down arrows. The frequency will step
up/down by 200Hz in voice-band modes and 20kHz in wide-band modes. Change the
step size by highlighting the step frequency (200/20k) and enter the desired step fre-
quency and press
DONE . To transmit a specific frequency tap on the frequency box
(right of TX), use the keyboard to enter the desired frequency then press Done To
change the TX level use the up/down arrow or enter the desired level by highlighting
