| Overload indicator |
this LED indicator warns of possible input
amplifier overloading. Without this indication it would be possible to introduce spurious
responses without knowing it. |
| SWEEP CHARACTERISTICS |
| Scan Width |
50 Hz to 50 kHz |
| Log Sweep |
20 Hz to 43 kHz ± 20% after 3 sweeps |
| Sweep Times |
0.1 s to 2000 s |
| Rep |
repetitive sweeps over the specified band |
| Reset |
resets to the beginning of the sweep-used to
adjust start or center frequency |
| Manual |
in combination with the concentric knob,
manual sweep fully duplicates the span of the electronic sweep |
| Adaptive Sweep |
when in adaptive sweep below the threshold
level, scan speed is 20 to 25 times faster. Threshold is adjustable to cover 0-60% of
screen. Signals greater than about 6 dB above threshold are detected and swept slowly. |
| Sweep Error Light |
this LED indicates a sweep that is too fast
to capture full response. When the light is on, response can be > 5% lower than it
should. |
| Zero Scan |
to look at the time varying signal at the
center or start frequency within the bandwidth selected, the zero scan is used. |
