Specifications
Specifications describe warranted instrument performance over the 0 to 55 °C temperature range unless otherwise noted. Specifications apply after the peak function has been performed. Supplemental characteristics
(indicated by italics) are intended to provide information useful in applying the instrument, but are not warranted parameters.

Switching time: 70 ms max
Stepped sweep mode
Resolution: settable 1 Hz, display 1 kHz
Accuracy: same as timebase
Minimum step size: same as resolution
Number of points: 2 to 1601
Switching time/point1: 7 ms + 8 ms/GHz step
Dwell time/point: 1 ms to 1 s
Ramp (analog, phase locked)
sweep mode
Resolution: 1 kHz
Accuracy (25 ±5 °C):
For 100 ms sweeps the greater of: ±.01% of span ±time
base or ±75 kHz ±time base
At other sweep speeds: [±.001% of span]/[sweep time
(s)] ±time base
Sweep time: 10 ms to 100 s; 400 MHz/ms max
Markers
10 independent continuously variable markers
Display modes: z-axis intensity
or RF amplitude pulse
Sweep functions
Start/stop, center frequency/span, marker, ramp,
stepped, manual, alternate and power sweep
Marker sweep: sweeps between markers one and two
Alternate sweep: alternates successive sweeps between
current front panel setting and stored setup
