Product Specifications

Amplitude Specifications

All receiver specifications apply from 10 Hz to 150 MHz and include 30 minute
warmup from ambient conditions unless otherwise noted. Typical performance is
applicable over ±5°C from the most recent autocalibration and is not warranted.
Supplemental characteristics are non-warranted functional and feature
information.

Amplitude measurement range

Maximum Safe Input Level: 50/75 Ohm 1M Ohm
Average Continuous Power: 26 dBm - (10 Hz to 150 MHz)
Combined AC/DC ±4 Vpk ±25 Vpk
Maximum Measured Input 20 dBm

Input range settings (characteristic only)

50 Ohm input (in 10 dB steps) +20 dBm to -20 dBm
75 Ohm input (in 10 dB steps) +22 dBm to -18 dBm w/included adapter
1M Ohm input 0 dBm (for reference impedance of 50 Ohm)

A/D overload level:2 dB (relative to selected range)

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 × log [1/noise bandwidth] dBc relative to the above graph.

Spurious Responses

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

Harmonic distortion

Low-distortion mode, 50 and 75 Ohm inputs: Harmonic distortion products
are <-80 dBc (<-90 dBc typical) for spectrally pure input signals with
total input power level = range. Degrade specification by 10 dB when
low-distortion mode is off.

1M Ohm input:<-65 dBc (<-75 dBc typical)

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.

1M Ohm input: <-65 dBc (<-75 dBc typical)

Degrade intermodulation distortion specifications by 10 dB (5 dB for 1 MOhm
input) when input frequency is less than 30 kHz.

Residual responses

Degrade specification by 10 dB when low-distortion mode is on.
Degrade 10 dB for 40 kHz spans in narrowband zoom mode.

Image, multiple and out-of-band 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

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 Specifications

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 accuracy is the sumofinitial accuracy, aging and
frequency counter resolution. Accuracy is measured with
frequency counter function.

Initial Accuracy Without opt. 001 With opt. 001

20 to 30°C ±0.5 ppm ±0.01 ppm

0 to 55°C ±3.0 ppm ±0.07 ppm

Aging ±0.25 ppm/mo. ±0.125 ppm/mo

*Add ±0.1 ppm if instrument is on < 48 hours

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 × (RBW ÷ 2) Hz/s

Narrowband zoom mode: >7 measurements/s (for spans >=10 kHz)

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.
