HP 355C
Coaxial
Step Attenuator
HP 355C Product Details
The HP 355C dc to 1000 MHz manual step attenuator provides precision step attenuation
in 1 dB steps from 0 to 12 dB. Attenuator sections are inserted and removed by
cam-actuated microswitches which keep lead lengths short. This design minimizes
stray capacitances and inductances, and keeps phase shift to a minimum. The HP
355C is a compact and rugged unit in which the component parts are rigidly positioned
and well-shielded so that neither stray pickup nor signal leakage is a problem.
It may be connected with the 355D in series to provide precision attenuation in
1 dB steps from 0 to 132 dB. Either terminal may be connected as input or output. Features:
- Low insertion loss and low SWR
- Negligible leakage
- 0 to 12 dB in 1 dB steps
- Standard BNC RF connectors
