Field programmable gate array (FPGA) based lossless data compression may be used in a test device such as a spectrum analyzer to efficiently reduce the data transfer rate and needed memory. Multi-channel IQ data may be flexibly recorded using multiple lanes of high data rate connections such as JESD204B/C and PCIe between an analog-digital-converter (ADC), the FPGA, and a processor. Bandwidth, sample rate, and/or bit number may determine the IQ data size. When the IQ data size is less than a product of the compression coefficient and the data transfer rate, the lossless compression may be skipped saving logic usage and power consumption in FPGA. Thus, depending on memory and transfer rate perspectives, a decision may be made whether the compression needs to be used or not.
