C A U T I O N None of the N2800/1/2/3A probe amplifiers can withstand the extreme
temperatures (–55°C to +150°C) that the N5450B can withstand. When using the
N5450B extension cable, do not subject the InfiniiMax III probe amplifier to extreme
temperatures.
C A U T I O N None of the other probe heads are designed for extreme temperature testing.
The N5449A includes one N2873A probe. The adapter is specifically tuned
for the N2873A probe. Similar probes (1 ΜΩ input) can be used. Other
probes may not meet the bandwidth specification.
C A U T I O N When using the N5450B extension cable, do not subject the InfiniiMax III probe
amplifier or probe head (other than the N5441A solder-in probe head) to extreme
temperatures.
Use the N5443A Performance Verification (PV) accessory
fixture to properly position the probe for PV testing.
