NOTE If you encounter problems with this section, refer to “Data Transfer Troubleshooting (N5182A, E4438C and E8267D Only)” on page 340.

The signal generator accepts finite impulse response (FIR) filter coefficient downloads. After downloading the coefficients, these user- defined FIR filter coefficient values can be selected as the filtering mechanism for the active digital communications standard.

Data Requirements

There are two requirements for user- defined FIR filter coefficient files:

1.Data must be in ASCII format.

The signal generator processes FIR filter coefficients as floating point numbers.

2.Data must be in List format.

FIR filter coefficient data is processed as a list by the signal generator’s firmware. See Sample Command Line.

Data Limitations

Filter lengths of up to 1024 taps (coefficients) are allowed. The oversample ratio (OSR) is the number of filter taps per symbol. Oversample ratios from 1 through 32 are possible.

The maximum combination of OSR and symbols allowed is 32 symbols with an OSR of 32.

The Real Time I/Q Baseband FIR filter files are limited to 1024 taps, 64 symbols and a 16- times oversample ratio. FIR filter files with more than 64 symbols cannot be used.

The ARB Waveform Generator FIR filter files are limited to 512 taps and 512 symbols.
