Custom Arb Waveform Generator

Working with Filters

To Create a User-Defined FIR Filter with the FIR Values Editor

In this procedure, you use the FIR Values editor to create and store an 8-symbol, windowed, sinc function filter with an oversample ratio of 4. The Oversample Ratio (OSR) is the number of filter coefficients per symbol.

You can define from 1 to 32 FIR coefficients, where the maximum combination of symbols and oversample ratio is 1024 coefficients.

The FIR Values editor allows a maximum filter length of 1024 coefficients, but the PSG hardware is limited to 512 symbols for arbitrary waveform generation, and 64 symbols for real-time waveform generation. The number of symbols equals the number of coefficients divided by the oversample ratio. If you enter more than the maximum number of symbols, the PSG cannot use the filter; it decimates the filter (throws away coefficients) until the required condition is met and then uses the filter, but fine resolution may be lost from the impulse response.

1.Press Preset.
