Power Requirements. The TPA-N-PRE
is powered directly from the RF input on
MDO4000 Series oscilloscopes.
Regulatory. Compliance labeling: WEEE
(European Union).
Recommended Oscilloscopes. MDO4000 Mixed
Domain Oscilloscopes
Note: For best probe support, download and
install the latest version of the oscilloscope
firmware from www.tektronix.com
Performance Verification
Since the TPA-N-PRE preamp is an accessory
to the MDO4000, its performance verification
(PV) procedure i
s a variation on the MDO4000
PV procedure.
To run the TPA-N-PRE PV, see the most
recent MDO4000 Series Oscilloscopes
