Digital Peak Capture: Displays the most positive measurement reading, which is
digitally held for indefinite display; PEAK and TRACK modes controlled by front-
panel button, rear-panel logic input, or computer-port command
Internal 15-Segment Linearization , programmable from front panel
Analog Output: Range scalable in 0.1% increments between 74.5% and 125.5% of
nominal input
Frequency Characteristics and Step-Response Settling Times: See "Analog
Filtering for Displayed Reading" for the Model 3540, above

Analog Peak Capture: Positive analog peak with minimum full-scale input pulse
duration of 6 msec (to 1% of full-scale accuracy), 12 msec (to 0.1% of full-scale
accuracy), and 20 msec (to 0.02% of full-scale accuracy); digitally held for indefi-
nite display; PEAK and TRACK modes controlled by front-panel button, rear-panel
logic input, or computer-port command
Internal 15-Segment Linearization , programmable from front panel
Analog Output: Range scalable in 0.1% increments between 74.5% and 125.5% of
nominal input. May be sourced by conditioned input (A) after the FIXED ANALOG
FILTER; (B) after PEAK CAPTURE; or (C) after the SELECTABLE ANALOG FILTER

* Initial (uncalibrated) inaccuracy may be as great as ±0.04% of full scale. Maximum error that
could occur upon replacement of the 3560 not followed by calibration is ±0.08% of full scale.
