BIN6030
Binary int16 values (in little endian byte order). The Keysight N6030 has 15 bits and
uses the most significant digits, ignoring the LSB. While importing, the 8 MSBs are
used as sample values, all other bits are ignored.
BIN5110
Binary int16 I/Q sample pairs (in little endian byte order). May contain full 16 bit DAC
values without the marker bits or 14 bit value plus two markers.
When importing 16 bit values without markers the marker flag should be set to ‘OFF’
so that the marker bits are ignored.
The first figure shows the bit mapping for the format without markers. The 8 MSBs
for I and the 8 MSBs for Q are imported to the M8195.
The second figure shows the bit mapping for the format with 4 markers. The 8 MSBs
for I, the 8 MSBs for Q and 2 of the 4 markers are imported. The marker M1 is loaded
into channel 3 and M3 into channel 4 of the M8195.
LICensed (SigStudioEncrypted in the SFP)
An encrypted file created with Keysight Signal Studio. This file contains I/Q sample
pairs, markers, and some other waveform information, from which all but the sample
rate is ignored.
This file type can contain 8 markers. Marker bits 4 to 7 are always ignored. Marker
bits 0 to 3 are mapped to the two markers M1 and M2 supported by the M8195A as
follows:
IONLy or BOTH:
Marker bit 0 is mapped to M1 (output on channel 3) and marker bit 1 is
mapped to M2 (output on channel 4).
QONLy:
Marker bit 2 is mapped to M1 (output on channel 3) and marker bit 3 is
mapped to M2 (output on channel 4).
In the first step the samples from the file are resampled from the input sample rate
found in the file to the sample rate set in the M8195A.The resampling method uses
the resampling mode selected by the TRAC:IMP:RES command.
In the second step if BOTH is selected, the I and Q samples are up-converted to the
carrier frequency (CARR:FREQ command) and written to the M819A waveform
memory. If IONLy or QONLy is selected, the I or Q samples, respectively, are directly
written to the M8195A waveform memory.
