SWEEP Menu Options
• Sweep Mode: Use the up and down diamond keys to select Stealth,
Stealth (SDA COMPATIBLE), Transmit, Transmit (SDA COMPATIBLE),
Loopback, or Sweepless. Table 4-1 lists the range of choices in each
mode for each of the SDA options.
• Sweep Limit Variable: The Sweep Limit Variable is x in the response
flatness expression (n/10 + x) used during sweep measurements to
compare actual system response to the formula. x is adjustable from 0.0
to 5.0 (the default is 1.0). Use the up and down diamond keys or the
numeric keypad to enter a value.
• Show Horizontal Markers: The horizontal markers continuously track
maximum and minimum values in the area of the graph between the
vertical markers (see Fig. 4-10). Use the up and down diamond keys to
display the markers.
• Forward Telemetry Frequency: Use the up and down diamond keys or
the numeric keypad to enter the forward telemetry frequency
corresponding to the SDA-5500.
NOTE: For successful Stealth mode operation, the SDA-
5000 telemetry frequency must match the transmit
telemetry frequency setting of the SDA-5500 transmitter.
CAUTION ! Do not place the telemetry signal too close to
the diplex filter cut-off frequency. Roll-off may attenuate the
telemetry signal to the degree that communication fails.
This same caution applies to placing the signal in the high-
end roll-off region.
• Forward Telemetry Frequency: Use the up and down diamond keys or
the numeric keypad to enter the forward telemetry frequency
corresponding to the SDA-5510.
NOTE: For successful operation, the SDA-5000 telemetry
frequency must match the forward telemetry frequency
setting of the SDA-5510.
CAUTION ! To prevent the SDA-5510 reverse sweep from
contending with the SDA-5500, disable the SDA-5500’s
