VDI - Erickson Power Meters (PM5B)
The VDI Erickson PM5B Power Meter is a calibrated calorimeter-style power meter for 75 GHz to > 3 THz applications. It offers power measurement ranges from 1 µW up to 200 mW. The PM5B is the de facto standard for > 100 GHz power measurement. The sensor head has a WR10 input and VDI sells a variety of input waveguide tapers for use at other frequencies. The VDI Erickson PM5B can typically be delivered within 9 weeks ARO or less. Contact VDI for more information.

PM5B: Compared to the PM5, the PM5B offers minor modifications and a CE mark. Contact VDI for more detailts.
PM4 to PM5B Upgrade: A cost effective solution is available to upgrade existing PM4 units to achieve the full performance of the PM5B. Upgrades of the PM3 systems are also available; however, although upgraded PM3 units will have improved performance, these may not achieve the full performance of a new PM5B. Contact VDI for more details.
|Typical PM5B Performance|
|Scale||90% Response Time*||RMS Noise|
|200 mW||0.15 sec||~0.02 µW|
|20 mW||0.2 sec||~0.08 µW|
|2 mW||0.6 sec||0.03 µW|
|200 µW||12 sec||0.003 µW|
to a response at the analog output of 90% of the final reading.

7. Pulsed Operation : The PM5B measures the average power from pulsed signals that have pulse rates faster than ~ 5 Hz (depending upon the scale used). The average signal power must be kept below 200 mW for safe operation, or the sensor head may be damaged. The peak power in the pulse can be as high as 10 W, but only if the duty cycle and pulse width are adjusted to maintain an average signal power below 200 mW. Please contact VDI for additional details or questions.
