Keysight 34959A User’s Guide 23
Environmental Voltage Limits
See the Introduction to the Plug In Modules chapter of the 34980A Mainframe
User’s Guide for detailed environmental operating conditions for the 34980A
mainframe and its installed modules. That guidance sets a maximum voltage
rating for the Analog Buses of 300V in pollution degree 1 (dry) conditions, and
derates the maximum voltage to 100V for pollution degree 2 (possible
condensation) conditions. That guidance applies to any circuitry installed in the
34959A module.
Module Cooling
The maximum recommended power consumption/dissipation for the breadboard
module and its installed circuitry is 6 watts, resulting in a 5
o
C rise in temperature.
CAUTION
Exceeding the maximum power limits for the 12V and 5V power supplies
(through improper wiring or cable damage) may cause the 34980A
mainframe to reboot. Although over-current protection is provided on the
power supply lines, operating in an overcurrent situation for extended
periods could damage the mainframe.
NOTE
To allow adequate cooling of the breadboard module, ensure that your circuit
layout does not impede air flow.
