The HP 8970A Noise Figure Meter, together with an appropriate noise source, automatically measures the noise figure and gain of the device to which it is attached. The Noise Figure Meter can be tuned between 10 and 1500 MHz. It can also be swept over all or any part of this range. To measure the noise figure of devices with output frequencies greater than 1500 MHz, an external mixer and local oscillator can be used to convert the frequency to the 10-1500 MHz range. Measured noise can be displayed as noise figure, equivalent input noise temperature, or Y-Factor. Gain is displayed in dB. Once calibrated, a single keystroke of the noise figure meter can automatically remove the measurement system noise and gain contribution. The noise figure analyzer then displays only the noise figure and gain of the DUT. The Excess Noise Ratio (ENR) of the noise source can be entered into the noise figure meter for up to 27 frequencies. The noise figure meter uses this data to correct for ENR versus frequency variations. Most functions can be remotely programmed via the Hewlett-Packard Interface Bus (HP-IB) and all measurement data is available to the HP-IB.
