리퍼비시 계측기
Featuring a low displayed average noise level (DANL) of typ. –159 dBm (1 Hz) at 2 GHz and –150 dBm (1 Hz) at 25 GHz without using a preamplifier, the R&S FSW measures spurious emissions quickly and reliably over a wide frequency range. DANL can be further improved by up to 13 dB by means of the analyzer’s switch-selected noise cancellation. Users can thus identify even the smallest of spurious emissions that were previously hidden in the noise floor, and effectively optimize transmit systems.
