Test Report

Test Data



Frequency Range 2 GHz to 18 GHz (Other Frequency Ranges Available)
Input Operating Range -18 dBm to -23 dBm (2-18 GHz)
Input VSWR 2.5:1 (2-18 GHz)
Threshold Level Internally Fixed to Provide a Minimum Signal Level of -23 dBm
Threshold Setting Stability +/-3.0 dB Over the Operating Temperature and Frequency Range
Maximum Power Input +10 dBm (Without Damage)
Detected Output The Detector Output Signal shall be a TTL Level high when the RF Signal applied to the RF Input exceeds the threshold level.  Any Signals below the Threshold Level shall result in an output level of TTL Low (0) the TTL output shall be buffered in such that output loading has no effect on detector response.  The detected output shall have a drive capacity of at least two standard TTL loads.
Response Time For any RF input greater than 3 dB above Threshold.  The maximum turn on response time measured at 90% RF to a TTL "1" output shall be 100 uS.  The maximum turn off response time measured at 10% RF to a TTL "0" shall be 100 uS.  (Units with higher speed of 10 nS, 25 nS, 50 nS, 50 nS, 100 nS, 100 uS. (Also Available as options HS10, HS25, HS50, and HS100)
