Description

The PG24192 is a PXI, Dual Channel Arbitrary Waveform Generator. It features fully differential outputs and a very low distortion. A programmable common mode voltage allows adapting to circuits that need a DC offset at their inputs. For single ended applications the positive output as well as the negative output can be used.

The unit is very suitable for audio type of measurements. The ranging is continuous from 10mVpp to 10Vpp with a resolution of < 0.1dB. The two channels are ideal for stereo and crosstalk measurements. There is a 1.2kHz low pass filter that reduces the harmonics for 1kHz signals to even lower levels. For most measurements the 22kHz filter is an excellent choice. If wide band operation is required the 100kHz filter can be selected.DC to 20kHz spectrum, 1KHz carrier, 96ksps, 22kHz filter (levels are dBc, carrier above 50dB not shown).

DC to 20kHz spectrum, 1KHz carrier, 96ksps, 22kHz filter (levels are dBc, carrier above 50dB not shown).

The internal clock sources can generate all standard audio sample rates and more. The External clock and trigger capability give the user full control of the measurement timing. If the PD24222 is used as digitizer, the clocks of the two units can be synchronized via the local bus capability of the PXI backplane. This allows coherent clocking for best measurement results.
