HP 85902A Burst Carrier Trigger for Digital Wireless Communications![]()
|
The HP 85902A burst carrier trigger provides a TTL timing reference that allows your spectrum analyzer to reliably trigger directly off the RF signal when performing transmitter tests. With an input range of 60 dB and a separate built-in preamplifier for greater sensitivity, you have the ability to trigger on a wide range of transmitter power levels.
For detailed specifications refer to the HP 85902A Product Overview literature number 5091-7292E.
