126 Agilent E8462A Specifications
Input Characteristics
These limits apply only if there are no connections made to power mains.
Maximum Input
NOTES:
a. Limited to 15,000 hours of voltage stress above 180V ACrms/DC (254Vpeak).
b. Replace the Crimp and Insert connector after 15,000 hours of operation of switching over
180V ACrms or 180Vdc. Refer to Chapter 1 of this manual.
c. Rating reduced to 30V ACrms, 42V ACpeak for exposed conductors.
Caution
When using the Option 012 Terminal Block:
The front panel connectors on the Agilent E8462A module must
be replaced after 15,000 hours of >180Vrms voltage stress due
to the close terminal spacing and the potential for pin-to-pin
leakage if the module regularly switches voltages greater
than 180VDC, 180VACrms or 254VACpeak/transient.
Caution
When using the Option 014 or Option 015 Terminal Block:
The ribbon cable header connectors on the Agilent E8462A
Option 014 or Option 015 Terminal Card must be replaced after
15,000 hours of >50Vrms voltage stress due to the close
terminal spacing and the potential for pin-to-pin leakage if the
module regularly switches voltages greater than 60VDC,
50VACrms, or 70.7 VACpeak.
