Field Sweeping with the SDA-5000: Considerations for Sweep in the Field

When the lower Start Frequency icon is highlighted, set the

lower frequency limit. Press the Enter key to begin, then use

the up or down diamond keys, or the numeric keypad, to enter

the frequency, and then press Enter again.

NOTE: Entering a value outside the sweep plan made in

the SDA-5500 will cause the start or stop frequencies to

default to the channel plan start or stop frequency.

Fig. 4-11 The SWEEP Frequency Screen

When the Stop Frequency icon is highlighted, set the upper

frequency limit. Press the Enter key to begin, then use the up or

down diamond keys, or the numeric keypad, to enter the

frequency, and then press Enter again.

You can return to values previously set with the icon in the lower

right of the display.

When you’re finished, press the soft key next to the Frequency

Submenu icon on the left side of the display to return to the

SWEEP screen.

Before you can store a reference sweep, you must wait for enough traces to

accumulate and verify a stable sweep. At that time, the icon (above and to

the left of 0dB at the top of the screen in Fig. 4-11), will disappear. The unit

has then developed stable data for use.
