Stability
Drift* (after warmup at stabilized
temperature)
Frequency Span (10 2 N
y
) MHz (2 2 N
y
) kHz/minute of sweep time*
* Because the analyzer is locked at the center frequency before each sweep , drift occurs only
during the time of one sweep . F or Line , Video , or External trigger , additional drift occurs while
waiting for the appropriate trigger signal.
y
N = LO harmonic . See \Frequency Range ."
Diagnostic IF Bandwidths
Shape Synchronously tuned four poles . Approximately Gaussian shape .
60 dB/3 dB Bandwidth Ratio IF Bandwidth
100 kHz to 3 MHz 15:1
30 kHz 16:1
3 kHz to 10 kHz 15:1
1 kHz 16:1
40 dB/3 dB Bandwidth Ratio IF Bandwidth
30 Hz to 300 Hz 10:1
