Type signature: (*->*)
Usage:
simulate-vcxo [OPTION]...
Allowed options:
Option | Description |
---|---|
--help | produce help message |
--pull-range arg (=1e-5) | pull range of simulated VCXO (units: relative frequency e.g. 1e-6 = ±1ppm) |
--latency arg (=0.1) | require pulse to be enqueued this early to succeed (seconds) |
--verbose | log all VCXO commands to console (default: only log failures) |
--start-stream-time arg (=9000.000000000000000000) | start output stream time at this value |
--start-input-stream-time arg | start input stream time at this value |
--min-sample-period arg (=0) | minimum width between plot points in seconds; plot points closer than this will be averaged |
--x-axis-unit arg (=sec) | unit of X axis (options: sec, min, hour, day) |
--x-axis-absolute | plot absolute stream time on X axis instead of relative to now (implied by --wait) |
--detrend | remove per-plot linear trend (due to clock frequency offset) from stream time offset plot |
--wait | wait for pipeline to terminate, then plot (default: live plotting) |
--live-history arg (=60) | duration of live history buffer in seconds |
--title-suffix arg | append string to plot titles |
--plot-x-axis-is-input-stream-time | make plot X axis correspond to input stream time (default: X axis is output stream time) |
--offset arg (=0) | simulate intrinsic oscillator frequency error by adding OFFSET to initial and commanded offsets (units: relative frequency e.g. 1e-6 = +1ppm) |
