$995.00

The 85685A is an analyzer from Agilent. Analyzers are key tools to test electronic equipment in the engineering, medical, automotive, and technological industries. Use analyzers for monitoring the performances of many different types of electronic devices. You may need analyzers for the measurement of components such as audio spectrums, voltages and currents, signals, and frequencies.

  • Attenuator range: 0 – 50 dB in 10 dB steps (nominal)
  • Linearity check: Add 3 dB (nominal)
  • Preamplifier gain: 20 dB (nominal) for 0 dB RFP attenuation

The 85685A preselector adds:

  • Automatic filter tracking
  • Input overload protection
  • Low system noise to the 8566B and 8568B spectrum analyzers

Add the 85685A RF preselector to the 8566B or 8568B general-purpose spectrum analyzer, and you have a test receiver for specialized applications. The RF preselector enhances these high-performance spectrum analyzers with tracking filters and preamplifiers that cover the 20 Hz to 2 GHz range. The spectrum analyzer/test receiver is sensitive to low-level signals while providing overload protection from out-of-band signals.

The result, for tests in the presence of high-level interference, is a measurement range 30 dB greater than that of the spectrum analyzer alone. (The improvement is even greater in the presence of broadband pulse-interference.)

The test receiver is easy to operate; simply use the spectrum analyzer controls without concern for preselector settings. The preselector automatically adjusts binput-filter tracking, and the spectrum analyzer reports preselector operating conditions on the CRT display. For remote operation with a computer, the receiver system is fully GPIB programmable (GPIB is hardware, software, documentation, and support for IEEE-488 and IEC-625, worldwide standards for interfacing instruments.)
