3.1 Initialization

Connect power supply then turn on the exciter. The initialization process takes about 5

seconds to finish while RF output level increases gradually to the pre-set value.

3.2 Query Mode

Query mode is a mode which displays parameters and status of exciter. There are three pages

in query mode. Press "Right" or "Left" button to switch between different pages which are shown

from Table 2 to Table 4 as below.

Note: All the displayed settings or numbers in below tables are for illustration only and may

be different from those in actual use.

Note:

1) The "TSNR", "LID" and "UID" in Table 2 are the measurement of feedback signal quality.

This feedback signal could be from a transmitter or the exciter itself and its input range is

from -30 dBm to 0 dBm (Recommended range is -15 dBm to -5 dBm). Feedback signal is

required to be connected port [RF_IN_A] ONLY. If there is no signal connected, these

readings will not be available or not valid. The "TSNR" is measured with equalization on. It

takes about 10 seconds to get the first reading on "TSNR", and about 3 seconds to get the

first reading of "LID" and "UID". After averaging, the "TSNR" display upper limit is shown

at about 39 dB and those of IMD are shown at about 54 dB.

2) The "CTRL" status in Table 4 has "RMT" (Remote) mode and "LCA" (Local) mode. When

in "Local" mode, the exciter can only be controlled by the front panel interface and when in

"Remote" mode, settings from the front panel keyboard are ignored - with the exception of

"RMT"/"LCA" setting, and only commands from remote control interface, such as serial port

or WEB, are processed.

3.3 Control Mode
