 HP 8970B Noise Figure Meter 
 Using the HP 8970B noise figure meter, measure the noise figure can become easy, accurate and repeatable. Automatic two amendments to the device even for low gain can be accurate noise readings. No external amplification or attenuation in the case, HP 8970B to allow for at least the dynamic around 40dB (in some cases, even higher) of the gain measurements, or up to-20dB of loss measurements. HP 8970B can store four ultra-noise ratio ENR (Excess Noise Radio) noise source calibration table. Can also measure the frequency of each appropriate interpolation ENR value. 

 Microprocessor and controller functions 
 HP 8970B noise figure measurements made no mystery. To achieve truly accurate, convenient and flexible noise figure measurements, using a microprocessor to calculate and necessary amendments. The instrument can also control an external local oscillator (such as the HP 8370 series synthesizers, HP 8340 or 8360 series or the HP 8350 synthesized sweep sweep oscillator source) and the HP 8971C Noise Figure Test Set. This makes the microwave frequency amplifiers, mixers, transistors accurate broadband measurement is as simple as RF measurements. 
 All HP 8970B's front panel keys and functionality are available through GPIB bus is IEEE -4 8 8 bus to operate. The instrument also has a separate system interface bus (SIB) to control the 8971C and the local oscillator. When used for automated testing device, this additional bus so that you do not have to write computer code to control the instruments on the SIB (eg, local oscillator). This ability can signal through other instruments through the instrument controllers on the bus to the SIB transmit information to any other instrument. 

 Front panel and special function 
 HP8970B the front panel keys to control the digital input, calibration and measurement. STORE, RECALL and SEQ key allows to store up to nine previous settings, and automatic or manual sequential implementation, in order to save setup time. Smooth INCREASE and DECREASE key is used to display up to 512 readings before the average, which will improve accuracy and eliminate display flicker. 
 For those who need more than a simple panel HP 8970B measurement capability can provide more operator, as long as one type of digital and special function keys can be selected by more than 200 more than the special features. Cold - Thermal measurement and automatic compensation for the loss of the device under test is input two real down. One special feature is a list, it quickly shows you the current use of the special features. Three out of the card can be used as instruments of small reference manual. It includes most of the special features, GPIB bus formats and codes, error messages, typical measurement settings.
