Acquisition Modules and Platinum Firmware Monitoring Operations
The sine-wave calibration section provides controls for selection of
components, duration, amplitude and frequency. Not all instruments support
calibration of individual components.
Note: The Amplitude value in all calibration dialogues refers to an
arbitrary full-scale output from the calibration circuitry. It can be
left at 100% unless clipping is observed, in which case it should be
reduced until an undistorted output is observed.
14.3.2.2 Instrument Control - Command line
Platinum provides both a high-level and a low-level interface to connected
digitisers. The low-level interface involves interacting directly with the
command-line of the digitiser and is described at the end of this section.
The high-level interface is provided by the adc­command command, which
takes a number of sub-commands as described below. Each command must
be directed to a specific sensor and this must be specified as the first
argument. When invoked with no arguments, or with the ­­help argument,
a list of available targets (referred to as “modules”) is displayed:
eam2010 ~ # adc-command --help
usage: adc-command [options...]
======== Available ADC modules ========
C914-3K55
C914-3K56
This is followed by a list of available sub-commands. In the descriptions
below, module should be replaced by a name from the list provided by
invoking adc­command ­­help.
