When probing differential signals, the + and – connection of the MX0100A probe head can be
N OT E
determined when the probe head is plugged into the probe amplifier. The + and - indicators
on the probe amplifier represent the + and - inputs on MX0100A probe head.
When probing single-ended signals, ensure that the - input of the probe amplifier is
connected to the ground of the DUT.
Extreme Temperature Testing with MX0100A Probe Head
The MX0100A probe head can withstand temperatures from –55°C to +150°C
thereby making it suitable for extreme temperature environments such as
temperature chambers. For extreme temperature testing, use the MX0100A probe
head with the N5450B InfiniiMax extreme temperature extension cable.
To know more about the N5450B extension cable and cautions associated with
using an InfiniiMax probe head in extreme temperature testing, refer to
Extreme Temp Cable Extension Kit"
The MX0100A probe head components may undergo discoloration when used
under high temperatures. Such changes do not, however, affect the probe head's
performance or measurement quality. The probe head maintains its specified
frequency response and bandwidth over the operating temperature range (–55°C
to +150°C), without any need for compensation or correction.

temperatures (–55°C to +150°C) that the MX0100A probe head
can withstand. Be cautious not to subject these probe amplifiers
to extreme temperatures. Using the N5450B extension cable with
the MX0100A probe head physically separates the amplifier from
the probe head and therefore eliminates the chances of
amplifier's exposure to extreme temperatures.
