Accepted Parameter Strings
Parameter String Data
Type
Description
"DitherRange" ViInt32
Range of offset dithering, in ADC LSB’s. May assume
values v = 0, 1…15. The offset is dithered over the range
[ -v, + v] in steps of ~1/8 LSB. For Averagers ONLY.
"FixedSamples"
ViInt32
For Threshold Gate type in AP240/AP235 Analyzers and
Peak
TDC
ONLY.
Number of samples transmitted for each point over
threshold. It must be a multiple of 4. 0 = No limit imposed.
"GateType"
ViInt32
For AP240/AP235 Analyzers and Peak
TDC
ONLY.
1 = User Gates
2 = Threshold Gates
"HistoTDCEnable"
ViInt32
For AP240/AP235 Averagers ONLY.
May assume 0 for not enabled and
1 to enable the simple TDC mode for the channel
"InvertData"
ViInt32
May assume 0 (no inversion) and
1 (invert data, 1’s complement).
"NbrMaxGates"
ViInt32
For Threshold Gate type in AP240/AP235 Analyzers and
Peak
TDC
ONLY.
Maximum number of gates allowed for each segment.
0 = No limit imposed
"NbrSamples" ViInt32
Number of data samples per waveform segment. May
assume values between 16 or 32 and the available memory
length, in multiples of 16 (32) as explained below.
"NbrSegments" ViInt32
Number of waveform segments to acquire. May assume
values between 1 and 8192.
"NbrWaveforms" ViInt32
Number of waveforms to average before going to next
segment. May assume values between 1 and 65535 (64K –
1). For Averagers ONLY.
"NbrRoundRobins" ViInt32
Number of times to perform the full segment cycle during
data accumulation. For AP240/AP235 Averagers and
Peak
TDC
ONLY.
"NoiseBaseEnable"
ViInt32
May assume 0 (no base subtraction) and 1 (base subtraction
enabled). It can only be enabled if the threshold is enabled.
For Averagers ONLY.
