• HIGHpass — High pass filter — The FREQuency:HIGHpass command
sets the - 3 dB cutoff frequency.
• AVERage — Averaged value — The AVERage:COUNt command specifies
the number of averages.
Unlike acquisition averaging, the math averaging operator can be
used to average the data on a single analog input channel or math
function.
If acquisition averaging is also used, the analog input channel data is
averaged and the math function averages it again. You can use both
types of averaging to get a certain number of averages on all
waveforms and an increased number of averages on a particular
waveform.
Averages are calculated using a "decaying average" approximation,
where:
next_average = current_average + (new_data - current_average)/N
Where N starts at 1 for the first acquisition and increments for each
following acquisition until it reaches the selected number of averages,
where it holds.
Filters operate on a single analog channel source or on a lower math
function.
• MAGNify — Operates on a single analog channel source or on a lower
math function.
• TRENd — Measurement trend — Operates on a single analog channel
source. The TRENd:MEASurement command selects the measurement
whose trend you want to measure.
• BTIMing — Chart logic bus timing — Operates on a bus made up of
digital channels. The BUS:YINcrement, BUS:YORigin, and BUS:YUNits
commands specify function values.
• BSTate — Chart logic bus state — Operates on a bus made up of
digital channels. The BUS:YINcrement, BUS:YORigin, and BUS:YUNit
commands specify function values. The BUS:CLOCk and BUS:SLOPe
commands specify the clock source and edge.
