Specifications
These specifications are v alid only under the following conditions:
The probe and amplifier have been calibrated at an ambient temperature of
23 ° ±5 °C.
The probe and amplifier are operating within the environmental limits
described in Table 4-6 on page 4-5 (the operating temperature limits are 0 °C
to +50 °C, unless otherwise stated).
The probe and amplifier have had a warm-up period of at least 20 minutes.
The probe degauss/autobalance routine has been performed after the
20-minute warm-up period, and thereafter whenever the PROBE
DEGAUSS/AUTOBALANCE light blinks.
The amplifier output is properly terminated into 50 Ω.
Specifications are separated into two categories: warranted specifications and
nominal or typical characteristics.

nted Specifications
Warranted specifications, Table 4-1, are guaranteed performance specifications
unless specifically designated as typical or nominal.
