DESCRIPTION
The ASNT_FS8151 frequency synthesizer can be used for test applications, design verification, andR&D environments. The main output ranges from 4 to 32GHz. There is a sync output for trigger ofthe equivalent time sampling oscilloscope. The main output clock amplitude is adjustable over anapproximate 3:1 amplitude range up to approximately 200 mV differentially at 32 GHz (frequencydependent). Outputs are K-type/SMA compatible female connectors. All operation and adjustment
controls are accessed by a GUI controlled interface connected through a USB port.

Sync Output
The sync output provides an AC coupled oscilloscope trigger. The trigger output will automaticallyadjust to be on the order of 100 MHz and an even submultiple of the output frequency. The user canalso set it manually to any divisor from 1 to 256, from the internal base frequency PLL output(before band-dependent frequency conversions).

Software Interface
The software provided with the ASNT_FS8151 provides a simple GUI interface to control output
frequency and amplitude through its on board USB port. The sync output division ratio can also be
selected here. This is shown in Figure 2.
Use the up and down arrows to increment and decrement the frequency, according to the frequency
step (also selectable). Or use the slider, or enter the digital frequency choice.
Tooltip help (hover over feature with mouse pointer) explains most of the features. Select Featuresfrom the menu to get the Features panel (Fig. 2).
Derived quantities are calculated, for testing convenience. RF On can disable the output. Snap toDetent keeps the frequencies to round numbers. Trig as alt out lets you use the otherwise syncoutput for generating frequencies from 100 kHz to 2 GHz. Extra Range and Precision gives you
adjustment in kHz increments more easily and auxiliary reach (with reduced duty cyclespecifications) down to 50 MHz. The Doubler Used indicator alerts to a frequency doubler being
used, and its impact on odd/even cycle duty cycle evenness.
