Remote Spectrum Monitor : How To : Set the Measurement Frequency
 
Set the Measurement Frequency
The frequency settings are displayed on the left and right bottom edges of the measurement display.
Using Start and Stop Frequencies
1. Select the Frequency tab.
2. Enter the start frequency in the Start entry box.
3. Click the Units list associated with the start frequency entry box.
4. Select the desired Unit - Hz, kHz, MHz, or GHz. Typing the first letter of the units after typing the number will display the corresponding unit in the Units list box. For example, typing 700M automatically enters 700 MHz.
5. Enter the start frequency in the Stop entry box.
6. Click the Units list associated with the stop frequency entry box.
7. Select the desired Unit - Hz, kHz, MHz, or GHz.
Entering Center Frequency
1. Select the Frequency tab.
2. Enter the center frequency in the Center entry box.
3. Click the Units list associated with the start frequency entry box.
4. Select the desired Unit - Hz, kHz, MHz, or GHz.
Entering Span
1. Select the Frequency tab.
2. Enter the center frequency in the Span entry box.
3. Click the Units list associated with the start frequency entry box.
4. Select the desired Unit - Hz, kHz, MHz, or GHz.
5. There are also buttons for Full Span, Last Span, Span Down, and Span Up.
Full Span: Sets the span to cover the entire tunable spectrum of the instrument.
Last Span: Returns the span to the most recent span value immediately before a change was made.
Span Down: Span Down 1-2-5. This is a convenient way to narrow the frequency span. The first time this button is pressed, the span value decreases to the nearest even value that starts with 1, 2, or 5. For example, if the span is 1.8 MHz, then pressing this button for the first time changes the span to 1.0 MHz, and the next press takes the value to 500 kHz, then 200 kHz, and so on.
Span Up: Span Up 1-2-5. This is a convenient way to quickly arrive at a wider span value. The first time the button is pressed, the span value increases to the nearest even value that starts with 1, 2, or 5. For example, if the span is 1.8 MHz, then pressing this button for the first time changes the span to 2.0 MHz, and the next press takes the value to 5.0 MHz, and so on.
