11 Signal Generator Mode
The SARK-110 can be used as a programmable RF signal source in Signal Generator Mode. It
outputs a sinusoidal RF signal at a frequency programmable from 1 kHz to 230 MHz with eight
user selectable amplitude levels ranging from -73 dBm to -10 dBm. In addition, frequency
sweeps can be programmed with linear, bi-linear, logarithmic, or bi-logarithmic functions.
This signal generator mode is ideal for receiver testing and alignment, sensitivity tests, RF signal
tracing and troubleshooting.
Use Navigator A to highlight «Mode» in the main menu. Press the Select [
■
] button to activate
the Mode popup submenu and use Navigator B to highlight «Signal Generator» submenu mode
option. Finally press the Select [
■
] button to enter into Signal Generator mode.
The screenshot below shows the signal generator screen in continuous frequency operation
mode. The screen includes the programmed frequency in Hertz and the output power level
expressed both in dBm and volts.
Frequency can be changed as usual; see chapter 4.4.
For changing the output level, use Navigator A to highlight «Level» in the main menu. Use
Navigator B to select the desired level or press the Select [
■
] button to activate the level
selection pop up dialog.
There are eight selectable output levels ranging from -73 dBm to -10 dBm. The «Maximum»
output level setting produces the device’s maximum output signal level that the hardware can
support at the assigned frequency. Note that when using this setting there is both a more
noticeable amplitude roll off with frequency as well as higher distortion of the output signal.
