17.2.3 Average / ERES
Average / ERES can be set in acquisition mode and arithmetic function as well, but with different
computing methods. Average and ERES in acquisition mode are computed by hardware with a higher
speed than if they were computed by software in the arithmetic mode. Average and ERES in acquisition
mode can only be based on data from analog channels, while the Average / ERES arithmetic function
can use analog channels, zoom traces, math, and memory traces as the source.
17.2.4 Max-hold / Min-hold
The value of Max-hold and Min-hold are based on statistical calculations from multiple frames. The
following figure shows the Max-hold result.
17.3 Algebra
The SDS6000L can perform algebraic operations including differential (d/dt), integral (∫dt), square root
(√), absolute(|x|), sign, exp (
), exp10 (
), ln, lg and interpolate (Intrp).
17.3.1 Differential
The differential (d/dt) operator is used to calculate the derivative of the selected source. It is always
used to measure the instantaneous slope of the waveform, such as the slew rate of an operational
amplifier.
