Temperature rating
U1818A/B probe amplifier have a specified operating temperature range of 0°C to
+50°C. However, the probe heads can be operated over a much larger range of
temperatures. If you need to make measurements at temperatures outside the
range of the amplifier, the N5450A Extreme Temperatures Cable Extension Kit is
your solution.
These cables can used to physically separate the amplifier from the probe head to
allow you to operate the prode head inside a temperature chamber while the
probe amplifier remains outside the chamber.
