Atec PMM-9010_9030_9060 - Manual (Page 11)

The same rechargeable plug-in battery
is used for all PMM 9010, 9030 & 9060
much better than any analogue receiver, as per the following table:
Unsurpassed Intrinsic Uncertainty
ANALOGUE TO DIGITAL UNCERTAINTY COMPARISON
Input Quantity Analogue uncertainty contribution PMM 9010 uncertainty
(typical) in dB contribution
Receiver reading ±0,1 Equal or better
Aging TBD, but present Absent
Attenuation:
Antenna-receiver ±0,1 Equal
Cables TBD, but present Absent
Connections TBD, but present Absent
Receiver correction:
Sine wave voltage ±1,0 Better
Pulse amplitude response ±1,5 Better
Pulse repetition rate response ±1,5 Better
Mismatch:
antenna-receiver +0,9/-1,0 Equal
antenna-cable TBD, but present Absent
cable-cable TBD, but present Absent
Cable-Antenna (or other
transducer, e.g. E.M. clamp)
±0,9 Better (w/ 9030-9060)
balance
Cables coupling to ground TBD, but present Absent with 9030 or 9060
Comparison between antenna-receiver connected by coaxial cable (blue trace) and PMM 9030 directly
connected to the antenna and linked to PMM 9010 by fiber optic cable (pink trace).
The example shows how PMM’s solution can prevent unwanted signals being picked up by the coaxial cable
along its path from the antenna to outside the chamber.
