This single-site module L-Band receiver accepts input ranging from 900 to 2200 MHz with input signal power ranging from -77 to +10 dBm. The software interface provided displays amplitude vs. time, amplitude vs. frequency (spectrum), and frequency vs. time (falling raster). Control of the L-Band receiver is also available via the software interface. The receive bandwidth is software-selectable from 1 to 65 MHz. Two ICE-LB2D modules can be placed on a single [[ICE-PIC7|ICE-PIC]] card for dual-channel applications using a single 8-lane PCI Express slot.

An internal 10 MHz reference can be used by selecting the onboard 10 MHz reference, or an external 10 MHz reference can be provided via an SMB connector. An SMB connector for external 1 PPS input is available. The external 1 PPS input is stored in bit 0 of a 16-bit word that is 14-bit Data MSB aligned. When used for the [[ICE-PIC7|ICE-PIC DSP card]], an IRIG-B002 (DC IRIG-B) stream can be received via an SMB connector on the ICE-PIC card for accurate time reference.
