Cable & antennatest

Large dynamic range

With dynamic range up to 125dB (IFBW=10Hz), 3656A/B/D is capable of accurate measurement on devices with high rejection ratio.

Large dynamic range

Network analysis

Frequency range of the network analysis is 1MHz~20GHz, frequency resolution is 10Hz. Analysis and measurement of full 4S-parameters vector network are all ailable. The analyzer can test full S-parameters of amplifiers, filters, attenuators and diplexers, etc., with display formats as logarithmic, linear, phase, impedance, polar coordinates and so on.

Network analysis

Spectrum analysis

Frequency range of spectrum analysis is 100kHz~20GHz. With the features of wide frequency band, high resolution, high level of sensitivity, large dynamic range, etc., it can acquire special info which cannot be easily obtained from time-domain measurement, such as spectrum purity, signal distortion, spurious signal, inter-modulation and so on.

Spectrum analysis

USB power measurement(option)

Users may choose 8723X Series USB Power Sensor produced by CETI for power measurement, which can test the RF/microwa signal power at the frequency up to 40GHz.

USB power measurement

Power Monitoring(option)

Frequency of power test ranges from 100KHz to 20GHz. And power measurement of signal is ailable by spectrum input port.

Power Monitoring

Vector Voltage Measurement(option)

Frequency range of vector voltage measurement is from 1MHz to 20GHz. The analyzer can achieve accurate test of cables or other pieces under test by deploying integration scheme instead of a traditional vector voltage meter.

TYPICAL APPLICATIONS

Test in multi fields:

  • Test of filter
  • Test filter specs like insertion loss, ripple wave, out-of-band rejection, etc..
  • Measurement of time domain
  • Test cable length and DTF by cable and antenna test or time domain of network analysis.
  • Test of radar and communication system
  • Measure radar cross parameters
  • Be used in the design of all kinds of military and civil radar systems to precisely test frequency, power and phase noise of all kinds of signals during R&D. It can also test different kinds of spurious signals, harmonic distortion and modulation characteristic of signals.
  • Monitoring and management of spectrum
  • Manage RF signals within the control range and identify and search all kinds of interfering signals, such as monitoring and management of military radio, broadcast station, communication equipment, airport, base station, and sensitive regions. Monitoring of radio is also available due to audio demodulation function of it.
  • Monitoring of communication satellite
