5080A/SC
Users Manual

General Specifications
All specifications are valid after a warm-up period of 30 minutes, or twice the time since last warmed up, to a maximum of
30 minutes. For example, if the 5080A has been turned off for 5 minutes, the warm-up period is 10 minutes.
Specifications include stability, temperature coefficient, linearity, line and local regulation, and the traceability of the
external standards used for calibration. It is not necessary to add anything to determine the total specification for the
temperature range indicated.

The square wave into 1 M
Ω
is a positive square wave from 1.8 mV to 55 V p-p. From 95 V to 105 V. Its output is a square wave-
like signal that alternates between the negative peak and the positive peak, with the centerline at -10 V. Signals between 55 V and
95 V p-p are not available.

The uncertainty of 50
Ω
loads does not include the input impedance error of the oscilloscope. Square wave signals below 4.5 mV
p-p have a specification of
±
(0.35 % of 300

Signals from 95 to 105 V p-p have a specification of 1 % of output in the frequency range 100 Hz to 1 kHz. Typical specification is
3 % of output for 95 V to 105 V p-p signals in the frequency range 45 Hz to 100 Hz.
