Dynamic range

Note: Dynamic range specifications apply with the source turned off.

Noise Level, 50 Ohm input (dBm/Hz using the marker noise function,

-20 dBm range)

The 50 ohm input noise level (dBm/Hz using the marker noise function,

-20 dBm range) will be typically -135dBc/Hz @ 1KHz and - 140 dBc/Hz

above 30 KHz to 100 MHz.

Specified for swept spectrum mode, with 50 Ohm input and low-distortion

mode off. Degrade 10 dB if in low-distortion mode and 2 dB if using

75 Ohm input.

For 1M Ohm input, noise is <-110 dBm/Hz below 40 MHz, with 1/f corner

at 100 kHz.

Input noise is degraded 4 dB in narrowband zoom mode for spans >10 kHz,

and 3 dB for start frequency <30 kHz.

Note: Equivalent noise bandwidth is narrower than 1 Hz for spans below

150 Hz in the narrowband zoom mode, providing additional reduction in

phase noise from that shown above. This maintains good dynamic range,

even for extremely small offset frequencies in narrow spans. Noise is

reduced by 10 x log [1/noise bandwidth] dBc relative to the above graph.

responses are <-70 dBc for signal levels = range. (<-80 dBc typical)

Harmonic distortion

low-distortion mode is off.

Degrade harmonic distortion specifications by 10 dB

(5 dB for 1M Ohm input) when input frequency is less than 30 kHz.



Intermodulation distortion

products are <-80 dBc (<-90 dBc typical) with respect to 2 tones 6 dB

below range. Degrade specification by 10 dB when low-distortion mode

is off.

Degrade intermodulation distortion specifications by 10 dB

(5 dB for 1 MOhm input) when input frequency is less than 30 kHz.


Residual responses

Input

The calibration procedures produce the greatest accuracy at 300 kHz.

Full-scale absolute accuracy at 300 kHz is ?}0.3 dB (0.1 dB typical)

when input level = range.

Accuracy is specified for manual frequency or for sweeps where sweep

time is increased by a factor of 4. Add ?}0.1 dB for autocoupled

sweep times.

Narrowband zoom: Measurement data is "windowed" in the FFT operation

of the narrowband zoom mode to optimize amplitude accuracy or frequency

resolution. This adds the following frequency response errors to the

full-scale absolute accuracy specifications.

High accuracy mode (Flat-Top window): ?}0.005 dB

High resolution mode (Hanning window): +0, -1.5 dB

Level is relative to the input range

Specifications are valid for frequencies >100 kHz.

Example: To compute the typical accuracy for a signal of -45 dBm at

100 MHz with 50 Ohm full-scale range of -20 dBm and manual sweep,

sum the typical full-scale absolute accuracy and scale fidelity.

i.e. (0.2 dB + 0.02 dB) = 0.22 dB


Input Port Return Loss: >20 dB


Frequency range

Specifications apply over the range of 10 Hz to 150 MHz

(10 Hz to 40 MHz for 1M Ohm input).

Frequency accuracy

Frequency Counter Resolution: 0.1 Hz

Drift/residual FM

Frequency drift and residual FM are negligible, as the Agilent 3588A is

fully synthesized (phase-locked to frequency reference) during

sweeps. For frequency accuracy during sweeps, see the accuracy

specifications above.

Measurement speed (maximum, characteristic only)

Sweep rate, oversweep off: RBW ?€ 2 Hz/s

Sweep rate, oversweep on: 4 x (RBW ?€ 2) Hz/s

Narrowband zoom (FFT): 400 ?€ span (Hz) seconds time record length

Note: Traditional analog RBW filters are usually swept at RBW ?€ 2 Hz/s

(or slower), to limit amplitude errors due to sweeping to <0.1 dB.

The oversweep mode of the Agilent 3588A provides up to 4 times faster

sweep times without increased error.
