Even Sec In
This field controls the internal connection of the EVEN SECOND
SYNC IN connector to the CDMA analyzer.
SYNC IN connector to the CDMA analyzer.
• When
Enable
is selected, signals applied to the EVEN SECOND
SYNC IN connector synchronize the timing circuits.
• When
Not
is selected, input signals applied to the EVEN SECOND
SYNC IN are ignored. This mode may be useful when signals other
than an even-second clock are used for synchronization. For
example, when using a one-second clock, you would select
than an even-second clock are used for synchronization. For
example, when using a one-second clock, you would select
Not
after
synchronization to prevent the internal even-second clock from being
retriggered half-way through its cycle.

Gain
This field sets the IF gain of the CDMA analyzer for rho, EVM, and
channel power measurements. (Range: 0 dB to 36 dB in 6 dB steps.)
channel power measurements. (Range: 0 dB to 36 dB in 6 dB steps.)
Gain is adjusted two ways:
•
Auto
measures the signal level and automatically adjusts the gain.
•
Hold
disables automatic operation to allow you to manually enter
the desired gain by selecting the current gain setting and entering a
new value using the keypad or cursor control knob.
