Circuit Descriptions

This chapter contains the overall instrument description and individual assembly descriptions for the Agilent 35670A Dynamic Signal Analyzer. The overall instrument description lists the assemblies in the analyzer and describes the analyzer’s overall block diagrams. The assembly descriptions give additional information for each assembly. For signal connections and descriptions, see chapter 9, ‘’Voltages and Signals.’’

Overall Instrument Description

The Agilent 35670A Dynamic Signal Analyzer is an FFT spectrum/network analyzer with a frequency range that extends from 0.19531 Hz to 102.4 kHz in single channel mode and from 0.097656 Hz to 51.2 kHz in two channel mode. The optional four channel analyzer has a frequency range that extends from 0.097656 Hz to 51.2 kHz in two channel mode and from 0.048828 Hz to 25.6 kHz in four channel mode. The analyzer has a built-in signal source providing random noise, burst random noise, periodic chirp, burst chirp, pink noise, and fixed sine. Measurements can be saved to an internal 3.5-inch flexible disk drive, an external HP SS-80 disk drive, or to internal non-volatile memory. Plots and prints of the measurements can be made directly to printers and plotters with GPIB, parallel, or serial interfaces. The analyzer also supports the Instrument Basic programming language (IBASIC).

channel analyzers. The A12 BNC assembly routes the signals connected to the Channel 1 BNC connector and Channel 2 BNC connector to the A1 Input assembly. The A12 BNC assembly also routes the source signal from the A5 Analog assembly to the Source BNC connector. The signal connected to Channel 1 should be between 0.19531 Hz to 102.4 kHz in single channel mode and between 0.097656 Hz to 51.2 kHz in two channel mode. The signal connected to Channel 2 should be between 0.097656 to 51.2 kHz. For both channels, the signal’s amplitude range must be between +27 dBVrms and –51dBVrms for full scale measurements. The source output signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine.
