11. RF SPECTRUM SCREEN
The RF spectrum screen displays the RF spectrum centered around the tuning frequency with frequencies above being positive and below being negative.
The amplitude and frequency scales are both adjustable and have cursors associated with them. The RF spectrum is maybe colored such that center
green represents the analog carriers, yellow the main HD carriers, and red the extended mode HD carriers.
SCREEN SELECTABLE DATA
To select a parameter click on the screen, then select the choice using the knob, and click again. Adjust the parameter using the knob and click to set the
new value. To exit this screen, select the screen icon and click on it.
dB: The dB amplitude scale is scrollable from +100.0dB to −150.0dB in increments of the selected major division.
VR: The dB amplitude resolution is adjustable from 0.1dB to 0.8dB per pixel.
C1: The C1 cursor is a horizontal amplitude cursor which is adjustable in VR steps.
HR: The frequency resolution is adjustable in steps of 50, 100, 250, 500, 1k, 1.5k, 2k, and 2.5 kHz per pixel.
C2: The C2 cursor is a vertical frequency cursor, which displays the amplitude value at the selected frequency. Frequency step size is determined by the
HR setting.
kHz: The spectrum frequency is scrollable in the current major division step size approximately ±1.0MHz around the tuning frequency.
12. COMPOSITE SPECTRUM SCREEN
The Composite spectrum screen displays the Composite spectrum from 0 to 150 kHz. The amplitude and frequency scales are both adjustable and have
cursors associated with them.
SCREEN SELECTABLE DATA
To select a parameter click on the screen, then select the choice using the knob, and click again. Adjust the parameter using the knob and click to set the
new value. To exit this screen, select the screen icon and click on it.
dB: The dB amplitude scale is scrollable from +100.0dB to −150.0dB in increments of the selected major division.
VR: The dB amplitude resolution is adjustable from 0.1dB to 0.8dB per pixel.
C1: The C1 cursor is a horizontal amplitude cursor which is adjustable in VR steps.
HR: The frequency resolution is adjustable in steps of 5, 10, 25, 50, 125, and 250 Hz per pixel.
C2: The C2 cursor is a vertical frequency cursor, which displays the amplitude value at the selected frequency. Frequency step size is determined by the
HR setting.
kHz: The spectrum frequency is scrollable in the current major division step size over the entire 0 to 150 kHz range.
