Resolution bandwidth

10 Hz to 3 MHz resolution bandwidths

are used in a 1, 3, 10 sequence. An

appropriate bandwidth is always

available to provide proper

resolution for any frequency span.

A narrow 10 Hz bandwidth makes

possible the resolution of 50 Hz

sidebands that are > 60 dB below

the peak of a 500 kHz signal, while

internal line-related sidebands

remain below the filter response.

Wide 1 and 3 MHz bandwidths with

"Gaussian" shapes improve sensitivity

and transient behavior when

measuring impulse noise, such as

electromagnetic interference, or

demodulating wideband spectra.

Dynamic range

The spurious-free dynamic range

measures > 80 dB with < –50 dBm

signal levels at the input mixer.

Harmonic and intermodulation

distortion products can typically

be measured > 90 dB below the peak

of a signal.

Single sideband phase noise

Single sideband phase noise is > 80

dB below the peak of a CW signal

at frequency offsets > 30 times the

resolution bandwidth setting, for

resolution bandwidths < 300 Hz.

Single sideband phase noise is

typically > 80 dB down and 200 Hz

away in a 10 Hz resolution bandwidth

at 1500 MHz.
