Issues and Errata¶
Errata are functional defects or errors, which may cause the product to deviate from published specifications. Documentation issues include errors, unclear descriptions, or omissions from current published specifications or product documents.
TRION and TRION3¶
ID001 - TRION(3)-18xx-MULTI Highpass Filters (0.16Hz - 100Hz) show 64% overshoot and higher cutoff frequencies than expected¶
Problem¶
Using the highpass filter of HS-MULTI (highspeed) boards show unexpected behaviour. The cutoff frequencies of the highpass filters are higher than the set frequency and the filters show 64% overshoot. These filters are calculated in the FPGA. The FPGA calcuation of these filter stages is not working properly.
Implication¶
For the 18xx-MULTI board the IEPE mode cannot be used properly for low frequencies. The input coupling is not working correctly in this frequency range. Highpass filters in ranges (0.16Hz - 100Hz) cannot be used properly. Modes with DC coupling can be used without issues
Workaround¶
Workaround in version 6.6. New AC-Coupling 0.15Hz
Status¶
Fixed in TRION Version 6.7.3
ID002 - TRION(3)-18xx-MULTI Highpass Filters (0.16Hz - 100Hz) is distorting the input signal¶
Problem¶
Using the highpass filter of HS-MULTI (highspeed) boards show unexpected behaviour. Since implementation of 10th order low pass filters in version 6.2 the TRION API sets wrong registers wrapping around to the address range of the highpass filter. Only the averager takes affect and the filter is not applied properly.
Implication¶
For the 18xx-MULTI board the IEPE mode cannot be used properly for low frequencies. The input coupling is not working correctly in this frequency range. Highpass filters in ranges (0.16Hz - 100Hz) cannot be used properly. The filtered signal is distorted. Modes with DC coupling can be used without issues. Boards without 10th order Filter are not affected.
Workaround¶
Workaround in version 6.6. New AC-Coupling 0.15Hz
Status¶
Fixed in TRION Version 6.7.3
ID003 - TRION3-1810M-POWER phase mismatch at low samplerate < 10 kHz¶
Problem¶
Using samplerates lower 10kHz and changing the Lowpass Filter Settings with TRION3-1810M-POWER boards show unexpected phase jumps of +-800ns between channels.
Implication¶
TRION3-1810M-POWER cannot be used properly for samplerates < 10 kHz
Workaround¶
Use samplerates > 10 kHz
Status¶
Fixed in TRION Version 7.2
ID004 - Phase mismatch of TRION-POWER-SUB-dLV-5V and TRION-POWER-SUB-dLV-1V¶
Problem¶
When using TRION-POWER-SUB-dLV-5V or TRION-POWER-SUB-dLV-1V, there is currently a phase shift of 1.5 microseconds in relation to the high voltage channels. This corresponds to a phase error of 0.027° with a 50 Hz signal.
Implication¶
There is an additional phase error when using the TRION-POWER-SUB-dLV-5V or TRION-POWER-SUB-dLV-1V for power measurements.
Workaround¶
Set the delay compensation of the affected channels to 1500ns.
Status¶
Fixed in TRION Version 7.2
ID005 - NEXDAQ High-Temperature Operation Instability¶
Problem¶
Starting from temperatures of 30°C/86°F Users may experience unexpected behavior, including but not limited to, system crashes, data corruption.
Implication¶
NEXDAQ cannot be used properly for in specified temperature range 30°C/86°F to 70°C/158°F.
Workaround¶
Ensure Proper Cooling: Provide Airflow to the device, in order to maintain operating temperatures within the safe range.
Status¶
Fixed in TRION Version 7.3
ID006 - TRION3-1810M-POWER / TRION3-18xx-MULTI: Artefacts After Setup Load¶
Problem¶
TRION3-1810M-POWER / TRION3-18xx-MULTI sometimes show artefacts (one sample jumps to full scale) on different channels, 10-100 ms after start when loading a setup. In very rare cases this is persistant.
Implication¶
Channels show artefacts after loading a setup.
Workaround¶
In case the artefacts are persistent, an OXYGEN restart is required.
Status¶
Planned fix in TRION Version 7.4
