TGR2050 Series Instruction Manual
NOTE
The best method of adjustment is by numerical scrolling, using either the rotary
knob or the
˄
& ˅
arrow keys on the front panel.
It is recommended that phase is adjusted first for minimum signal followed by
amplitude, repeating the process until the required suppression is achieved.
The same process is applied to carrier suppression at 25MHz below the currently set
output frequency above 250MHz and at 25MHz above the set output frequency at
250MHz or below.
The I and Q offset adjustments are interactive and must be adjusted iteratively until
the required suppression is achieved.
Once all the IQ trim parameters have been adjusted, touch

save and exit back to the Utility menu.

The options are

or
Cancel
