SPECTRUM ANALYSER TOOLKIT IS DISCONTINUED FROM AUGUST 2021 DUE TO CRITICAL COMPONENT OBSOLESCENCE. WE HAVE SUFFICIENT COMPONENTS PUT BY TO SERVICE AND MAINTAIN EXISTING CUSTOMER INSTRUMENTS.

SAT1 and SAT1 PRO

Applications

• Preamplifier and receiver sensitivity peaking, noise figure and gain measurements
• Ultrahigh sensitivity testing, reduce your spectrum analyser noise floor below -170dBm/Hz with the flat high gain VLNA
• Precise noise figure alignment using the pulsed noise mode
• Turn your spectrum analyser into an ultra sensitive spectrum monitor / panoramic receiver with high dynamic range
• Provides much faster sweep times on wider spans for a given noise floor by selecting wider resolution bandwidth settings
• Noise source plus VLNA provide a flat power source … tracking generator substitute
• Two port response sweeping of amplifiers, filters and cables
• Flat noise source signal generator provides rapid audible confidence checking of receivers HF ... 2400 MHz
• Noise figure testing of receivers through the audio output
• Education tutorial experiments demonstrating noise figure in circuits and noise temperature in radio system engineering
• Screening effectiveness testing, e.g. screened room validation
• EMC testing requiring ultra low noise floor

Features at a glance
Calibrated noise source, stable, broadband and flat

• 2 MHz … 2400 MHz
• 10dB ENR +/-0.5dB ( -104dBm/MHz)
• 50 ohm sma output
• VSWR <1.15:1 noise on or off (RL >23dB)
• Pulse mode frequency 5Hz
• Y factor NF look up graph (see data sheet)

 
Very Low Noise Amplifier, stable, broadband and flat

• 30 MHz … 2 GHz  (20 MHz to 2.5 Ghz with reduced gain)
• 32dB gain; <+/-2dB flatness to 2 GHz (typically 32.5dB +/-0.9dB 30 MHz to 1.5 GHz)
• <1dB noise figure to 1.5 GHz (<2dB @ 2.5 GHz)
• -1dB compression +10dBm;  <+13dBm saturated
• Ofcom have dozens of our VLNA for spectrum monitoring applications using a spectrum analyser

Designed to provide a variety of additional features to your spectrum analyser. Regardless of the model of spectrum analyser you use, SAT1 unlocks new measurement capabilities up to 2 GHz with a broadband precision noise source plus a unique instrument grade VLNA design (>30dB gain, very flat from 30 - 1500 MHz and <1dB noise figure).
