GT-8551B Series USB Peak Power Sensor 100 MHz to 8 GHz, operational to 10 GHz Technical Information Specifications apply over 0 ºC to 50 ºC unless otherwise indicated. Typical specifications describe expected but non-warranted performance. Frequency Range Sensor Model Dynamic Range Sensor Model GT-8551B Dynamic Range from 8 GHz to 10 GHz is typically -30 dBm to +20 dBm Maximum Peak Power (Damage Level) Sensor Model Maximum input power: +20 dBm Maximum input voltage: 25 Vdc VSWR Sensor Model GT-8551B Recommended Calibration Cycle Recommended calibration cycle is one (1) year

Accuracy Measurement uncertainty is computed from the individual cal factor, mismatch, linearity, noise and temperature error factors, and can be computed as either worst case (sum of the applicable error terms) or RSS, representing the most probable error, where RSS is the square root of the sum of the squares of the error terms. Accuracy is typically < 2% (RSS) mid-band with source VSWR 1.2:1 (or better) at 25 ºC +/- 5 ºC. GT-8551B Error Factors Calibration Factor Note 1: Noise measured with a 1 second integration time. Zero Offset

Trigger Functions Rate Trigger Source Internal Trigger Signal Level Range Trigger Input TTL compatible, Rising or Falling Edge Trigger Input Operating Levels Trigger Input Maximum Levels Trigger-off Time Note 3: If the internal trigger is set to detect the rising edge of a pulse-modulated signal, then the signal pulse-off time must be greater than 1 µs for reliable triggering. If the internal trigger is set to detect the falling edge of a pulse-modulated signal, then the signal pulse-om (or Pulse Width) must be greater 1 µs for reliable triggering.
