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.
Frequency span range
(characteristic only)
Swept spans:
Range: 10 Hz to 150 MHz, and zero span
Resolution: 0.1 Hz
Accuracy: Greater of 0.1 Hz or .125% of span
Start/stop freq: 0 Hz to 150 MHz
Narrowband zoom spans:
Range: 1.23 Hz to 40 kHzin ×2 steps
Accuracy: ±0.001% of span
Resolution bandwidth
Swept spectrum: 1.1 Hz to 17 kHz ±10%
Narrowband zoom:
High-accuracy mode: 0.90% of span (11 mHz-360 Hz)
High-resolution mode: 0.37% of span (4.5 mHz-148 Hz)
Bandwidth selectivity
(shape factor or ratio of -60 dB to -3 dB bandwidths)
