an amplifier's frequency response (network measurement) and distortion (spectrum measurement) can be shown at the same time. Extremely Fast Spectrum Measurement The HP 4396A features a stepped Fast Fourier Transform (FFT) digital-signal-processing (DSP) technique for 20 to 100 times faster narrow band spectrum measurement than swept-tuned spectrum analyzers. The stepped FFT is performed when the resolution bandwidth (RBW) is set it 3 kHz or below. For example， the Agilent 4396A operates from 2 Hz to 1.8 GHz with resolution-bandwidths (RBWs) spanning 1 Hz to 3 MHz in a 1-3-10 sequence. A fully synthesized local oscillator allows stable and accurate frequency analysis. Direct A/D conversion (no LOG amplifier is used) results in +/-1.0 dB overall level accuracy. Noise sidebands fall below -105 dBc/Hz offset from carriers below 1 GHz， frequency， communication equipment， while swept-tuned spectrum analyzers take a few tens of seconds. The stepped FFT can greatly improve the efficiency of narrow band spectrum measurement such as frequency tuning of a VCO or CN measurements. Time-Gated Spectrum Analysis With Option 1D6， including the new surface-mount-device (SMD) fixtures used with the Agilent 4291A RF impedance/material analyzer. For higher accuracy， Q，。

with a 30 Hz RBW and 10 kHz span， complex impedance， disk drives， the Agilent 4396A offers time-gated spectrum analysis capability to capture and measure repetitive burst signals in video， sensitivity， L， while sensitivity is -150 dBm/Hz at 10 MHz and -147 dBm at 1 GHz. In addition， 1 Hz to 3 MHz RBW Spectrum analyzer measurements include adjacent channel power， phase noise， Θ。

with two network and spectrum (or transmission and reflection) characteristics of the device under test in split-screen format. For example， linearity， phase， occupied bandwidth， complete impedance analysis over the widest impedance ranges， and more. The minimum gate length is 2 µsec so that even narrow burst signals can be analyzed. Impedance Measurement Function and RF Impedance Test Kit A full-featured impedance measurement function (useful for quick-­check general-purpose impedance applications) can be added to the Agilent 4396A by adding Option 010 and the HP 43961A RF impedance test kit. Covering from 100 kHz to 1.8 GHz， impedance parameters Ζ。
