Manual sweep: <4.0:1
Auto-coupled sweep: 4.3:1 (typical)
Auto-coupled oversweep: 5.1:1 (typical)
Narrowband zoom mode
High-accuracy mode: 2.6:1
High-resolution mode: 9.1:1
Narrowband zoom (FFT) equivalent noise bandwidth
High-accuracy mode: 0.955% of span
High-resolution mode: 0.375% of span
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.
HP-IB binary trace output: approx. 120 ms/trace
