Agilent / HP / Keysight 8970B

The Agilent/HP 8970B Noise Figure Meter is used for measurements in the frequency range of 10 to 1600 MHz (2047 MHz optional). The 8970B saves precious time, money, and resources, since the measurements are done quickly, accurately, and with less chance of mistakes.

The Agilent 8970B controls an external LO for receiver or microwave measurements, controls the noise source to turn it "ON" or "OFF" and makes the noise power measurements.

The Agilent 8970B also calculates the noise figure, removes the effects of the measurement system's noise, compensates for losses before or after the DUT and displays the results in either noise figure, effective noise temperature or Y factor.

In addition, the wide dynamic range of the HP 8970B allows simultaneous gain measurements up to 40 dB or loss measurements to 20 dB, with no external attenuation or amplification.

The low instrumentation uncertainty (±0.1 dB) and measurement stability of the HP 8970B gives confidence in your noise figure results. Automatic second-stage correction makes accurate noise figure readings possible even for low gain devices.

The operating frequency of the Agilent 8970B can be extended from 1600 MHz to 2047 MHz with option 020 and measurements can be made directly, with no external downconversion.

Many components and receivers require noise figure measurement at frequencies greater than 1600 MHz. If you already own an HP 8970B Noise Figure Meter, you don't need to worry about building a custom down-converter to measure noise figure at microwave frequencies.

The HP 8971C combines, in one easy-to-use package, all of the components necessary for microwave downconversion to the HP 8970B's frequency range (10 to 1600 MHz). Accurate broad band measurements from 10 MHz to 26.5 GHz are possible with a single calibration and sweep.

Option 001 adds Agilent 8970B an internal LO power amp, reducing the LO input power
requirment of the HP 8971C from +7 dBm to +1 dBm. This option is usually required for measurements above 20 GHz, where source power becomes limited or in system applications, where there is considerable loss between the LO source and the 8971C LO input.

Option 002 deletes the built-in low noise RF preamplifier. This option is best suited for measurements of high gain devices or for measurements with a user-supplied low noise RF preamp.
