1Press [PRESET]. (Factory Preset)
2Input a signal (1 GHz,
3Set the center frequency to 1 GHz and the span to 5 MHz:
4Press [MARKER] > {More (1 of 2)} > {Mode} > {Freq Count} to turn the frequency counter on.
5Move the marker by rotating the knob, half- way down the skirt of the signal response.
6Press [MARKER] > {More (1 of 2)} > {Mode} > {Normal} to turn off the marker counter.
