Start Ref Cal
This button, when selected, will initiate the calibra-
tion of the synthesizer’s TCXO internal reference. The process will
take approximately six minutes to complete and while in process,
the indicator to the right of the button will blink. After the reference
calibration is completed, the indicator will remain on.
When the reference calibration is successful, the calibration data
will automatically be stored in the synthesizer’s permanent memory
and the date of calibration will be updated. If the reference calibra-
tion fails, the previous calibration data is retained and no changes
are made to the calibration date.
Synthesizer Frequency
This rotary control (along with an entry
box) is used to select a fixed frequency. A frequency value may be
selected by pointing the rotary control and dragging it around to
the left or right until the desired frequency is reached. The Locked
indicator will illuminate when the synthesizer settles on the target
frequency. The value is displayed in the entry box below the rotary
control. The entry box value may be changed by highlighting
the number and entering in the desired value or by using the up/
down arrows to the left of the entry box. The default frequency is
10,000 MHz. Refer to the synthesizer’s data sheet for applicable
frequency range. Data sheets are located on the Ni Microwave
Components website (www.ni-microwavecomponents.com).
Lock Recovery
When this check box is selected, the synthesizer
will automatically attempt to recover a lost or unestablished frequency
lock. Three attempts will be made to recover the lock. The Locked
indicator will no longer illuminate if the synthesizer cannot recover
the frequency lock. The lock recovery function is on by default.
Locked
This indicator illuminates when the synthesizer settles on
the target frequency.
RF Output
This button enables the user to choose between RF power
output on or off. By default the RF Output button is off. The button will
illuminate when on.
NOTE
Connect a 10 MHz reference standard to the REF IN connector on the front panel of
the synthesizer before starting the reference calibration process.
