Applicos: PG24192 PXI Dual channel 24-bit / 192ksps Arbitrary Waveform Generator

The PG24192 is a PXI, Dual Channel Arbitrary
Waveform Generator.


Product Introduction

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. 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.
