Introduction
Specifications describe warranted performance over the
temperature range of 0° to 45°C (except where noted)
and include a 30-minute warm-up from ambient conditions, automatic calibrations enabled, auto-zero on, time
domain calibration off, and anti-alias filter in, unless
noted otherwise. Supplemental characteristics identified
as “typical” or “characteristic,” provide useful information by giving non-warranted performance parameters.
Typical performance is applicable from 20° to 30°C.
When enabled, automatic calibrations are periodically
performed to compensate for the effects of temperature
and time sensitivities. During the calibration, no signals
> 0 dBm should be connected to the front panel inputs.
Definitions
Analog demodulation mode = Measurements with AM,
PM, and FM demodulation capabilities.
Baseband time = Time-domain measurements
selected by setting start frequency to exactly 0 Hz or
choosing full span in 0 to 10 MHz measurements.
dBc = dB relative to input signal level.
dBfs = dB relative to full scale amplitude range
setting. Full scale is approximately 5 dB below ADC
overload.
FS or fs = Full scale; synonymous with amplitude range
or input range.
RBW = Resolution bandwidth.
Scalar mode = Measurements with only frequency-
domain analysis available. Frequency spans up
to 10 MHz.
SNR = Signal to noise ratio.
Vector mode = Measurements with frequency- and time-
domain capabilities. Frequency spans up
to 10 MHz.
Zoom time = Time-domain measurements selected by
setting frequency parameters using center
frequency and span values.

a function of span. In vector mode, the minimum resolution bandwidth is a function of span and the number of
frequency points, and the maximum resolution bandwidth is a function of span only.
