In order to be able to better cover the whole parameter space for NI and WI etalon we have implemented the possibility to add a noise (i.e. a ramp or a sine) on the set point for the Etalon control.
Example for NI:
# name - unit - rampTime - sampFreq - value
ACL_CONST_CH "offset_noise_ni" "V" 1. GENE_FREQ 0
# nameOut - unit - rampTime - sampleRate - ramp ampl - ramp Freq - zero(%) - rise(%) - one(%) - fall(%) - offset(unit)
ACL_RAMP_CH "ramp_noise_ni" "V" 1. GENE_FREQ 0.01 1 0.001 49.999 0.001 49.999 0.00
# nameOut - unit - rampTime - sampleRate - sinus ampl - sinus Freq(Hz) - phi0(rad) - offset(unit)
ACL_SINEWAVE_CH "sin_noise_ni" "V" 1. GENE_FREQ 0.0 1e-6 0.0 0.0
# nameOut - unit - rampTime - sampleRate - ampl - seed
ACL_NOISE_CH "white_noise_ni" "V" 1. GENE_FREQ 0.0 0
# nameOut - Unit - rampTime(s) - sampling Frequency(Hz) - nameIn - slope - FilterName # Input sampling freq(Hz) - Working Filter freq(Hz)
ACL_FILTER_CH "color_noise_ni" "" 1 GENE_FREQ "white_noise_ni" 1 ETALON_NOISE_FLT
# nameOut - unit - rampTime - list weights/channels - Noise at the GENE_FREQ frequency
ACL_SUM_CH "NOISE_NI" "V" 1. 0. offset_noise_ni 0. ramp_noise_ni 0. sin_noise_ni 0 white_noise_ni 0.0 color_noise_ni
ACL_SUM_CH "NI_RH_SET_NOISE" "V" 1. 1. NI_RH_SET 0. NOISE_NI
ACL_OP_CH NI_RH_IN "C" "sum-" NI_RH_SET_NOISE NI_RH_INPUT
Now the NI_RH_SET_NOISE is also available on the data.
