QuickSyn Frequency Synthesizer
Model Number, Serial Number, Calibration Date, Options,
Firmware Ver
The information area, located in the upper-right
corner of the Main Control panel, reveals the Synthesizer’s model
number, serial number, date of last calibration, currently installed
options, and firmware version. This information cannot be changed
with the Soft Front Panel.
External Reference Indicators
When an external reference
source is connected to the Synthesizer, the Synthesizer will
detect the (10 MHz) reference signal and lock to the source. The
DETECT and LOCK indicators will illuminate.
Reference Source
These buttons are used to select between
External and Internal reference sources. Internal is the default
selection.
• When External is selected, the Synthesizer will detect and lock
to the user-supplied 10 MHz external signal.
• When Internal is selected, the Synthesizer will lock to its oven-
controlled crystal oscillator.
To lock to an external reference, connect an external reference
source to the REF IN connector located on the Synthesizer’s front
panel (see Figure 32) and select the External button.
Internal Reference
The OUTPUT button enables the user to
choose between reference power output on or off. By default the
OUTPUT button is on and illuminated. When the OUTPUT button
is off, the signal is muted, and the OUTPUT button is no longer
illuminated.
NOTE
External reference frequency input must be within 10 MHz ±2 ppm.
NOTE
Please have the information from the main control panel readily available when
contacting NI Microwave Components regarding questions about your Synthesizer.
