The input signals are digitised via the multiplex method. All 16 channels may be utilised as single-ended inputs. The maximum sampling rate is 500 kHz at 16-bit resolution (400 kHz for multiple channels). The maximum bandwidth per channel is 22 kHz, with a direct current (DC) baseline. In single-ended mode, the option of AC coupling is also available, as is a constant current sensor supply for IEPE-type sensors.
The input voltage ranges are 0.125V to 10V, encompassing eight discrete steps, and may be configured as either bipolar or unipolar. The RogaDAQ16’s highly flexible signal conditioning and connectivity make it an optimal choice for the majority of measurement applications.
In addition to the analogue low-pass filters, the system can utilise integrated oversampling filters (up to 16x, dependent on channel count and sampling rate) to enhance the rejection of noise, distortion and out-of-band signals. No further hardware is required, thus avoiding signal degradation caused by cabling, contacts and add-on signal conditioners.

ANALOG OUTPUTS
RogaDAQ16 offers four analog outputs. The output sampling rate is 100 kHz per channel at 16 bit resolution. The output voltage ranges are 0V-10V und ±10V. They can be used as generator outputs, monitoring outputs or for control loops. It is also possible to download data to RogaDAQ16 and output it to the D/A converters time synchronized by the DSP.
TRIGGERS
There are several trigger options available: Level, edge, limit or window conditions. It is even possible to use mathematically processed data for triggering (e.g. steepness of slope). Trigger conditions can start or stop a measurement, set digital outputs or control analog outputs. Several trigger conditions can activate or deactivate each other. So a network of dynamic triggers is possible, automatically adjusting to the current condition.
DIGITAL IN-OUT
There are 24 digital inputs / outputs available. Any of these ports may be individually controlled by the DSP as input or output.
The digital inputs optionally support counter, pulse width, period length or frequency counter. Incremental encoders can also be supported on request.
The outputs can optionally be used for PWM signals with a resolution of 100ns and output frequencies between 2Hz and 2,500,000Hz with zero pulse discontinuities. Modulation of frequency and pulse width is supported at the same time and independently. It is fully transparent to the user, who only specifies a frequency and pulse width in percent.
SOFTWARE
One of the most important criteria for modern measurement systems is software support. Even the most powerful hardware is useless without respective drivers.
RogaDAQ16 uses an optimized concept which ensures extensive application software support and easy adoption to new software environments.
Besides free of charge drivers for most common measurement applications like EVApro, DIAdem, LabView or DASYLab, further application programs are available.
