Description

GW Instek GSP-818 Spectrum Analyzer 1.8 GHz

GW Instek GSP-818 is a new general spectrum analyzer which supports a frequency range of 1.8 GHz and provides testing requirements for RF products during the development/production phases. It has a built-in 20 dB amplifier and it provides an adjustable range of resolution bandwidth from 10 Hz to 3 MHz. In addition, it has the AM/FM signal demodulation function and the ACPR/OCBW/CHPW test functions to meet the requirements of general RF signal measurement.

Features:

  • Frequency Range: 9 kHz...1.8 GHz
  • RBW: 10 Hz, 20 Hz, 30 Hz, 40 Hz, 50 Hz, 60 Hz, 70 Hz, 80 Hz, 90 Hz, 100 Hz, 200 Hz, 300 Hz, 400 Hz, 500 Hz, 100 kHz, 200 kHz, 300 kHz, 400 kHz, 500 kHz, 1 MHz, 3 MHz
  • Sensitivity: -148 dBm/Hz typical (PreAmp On)
  • Built-in AM/FM demodulation
  • Bandwidth zoom function
  • Measurement function: ACPR/OCBW/CHPW, NdB Bandwidth, Freq. Counter, Noise Marker, Limit Line
  • Built-in 20dB preamplifier standard
  • Interface: Lan, USB
  • Screen: 10.4" SVGA Output (800 x 600)
  • Options: Tracking generator, EMI filter & detector (via software keycode)

Applications:

  • Checking and analysis of spectrum characteristics
  • Analyze AM and FM signal characteristics
  • Monitor the signal uploaded by SNG vehicle
  • For a compact test system
