Used HP8901B modulation analyzer instrument JMM2500 modulation table offset price

Product Name: modulation analyzer HP8901A / B Brand: HP Product Model: 8901A / B Product Specifications: 150KHz ~ 1300MHz Product Information: Agilent 8910B Modulation Analyzer combines multiple RF functions of the instrument, capable of 150Khzg-1300MHz frequency range The modulated signal is comprehensive, accurate characterization. 8910B can perform precise measurements of modulation, recovery of the modulating signal, determines the RF frequency and RF power measurement. You can count on the 400Hz and 1kHz audio signal and measure the distortion. And can be adjacent channel power measurements or carrier-to-noise ratio measurement (with optional 030-037). 8910B is a fully automated instrument, simply press a button or via GPIB control, will be able to complete all measurements. Transmitter testing 8901B transmitter measurements have completed the required standard features. It can complete transmitter power measurement, frequency counts and accurate measurement of signal modulation, but also to determine the frequency of the demodulated audio signal level and distortion. With Option 030,8910B can quickly and accurately perform adjacent channel power measurement in accordance with CEPT standards. Characterization 8901B RF signal is accurately characterizing RF signal good laboratory and manufacturing equipment. Use 8901B, capable of phase-sensitive device and a web-sensitive device, such as a band-pass filter and a multichannel receiver for precise AM / FM and FM / AM conversion measurements. Excellent isolation between AM and FM so that distinction AM stereo AM and FM, AM and FM FM transmitter component of parasitic AM signal is very simple as well as complex. 8901B automatic measurement system is a major component of automated RF test system. All functions are fully automated and easy to program. Because of the many measuring binding to a single instrument, it can reduce the requirements for instrument interconnection, reducing hardware costs and reduce software development time.
