Available in 2-channel and 4-channel configurations, the RazorMax Express combines 16-bit vertical resolution with 700 MHz analog bandwidth (on 1 GS/s models) and a dual-port onboard memory architecture that supports sustained data streaming to the host PC at rates up to 6 GB/s over a PCIe Gen3 x8 interface. The datasheet identifies application areas including wideband signal analysis, RADAR design and test, signals intelligence (SIGINT), ultrasonic non-destructive testing, LIDAR systems, communications, optical coherence tomography, spectroscopy, high-performance imaging, time of flight, life sciences, and particle physics. A digitizer in this class converts analog input waveforms into time-sampled digital data so the captured signal can be analyzed, recorded, or processed by a host computer or onboard FPGA. ValueTronics International operates from a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where every instrument is received, tested, graded, and prepared for shipment by our own technicians before it leaves the building. We are not a drop-shipper or a pass-through broker: the digitizer you order has been physically inspected at our facility, its specifications verified against published manufacturer data, and its accessories confirmed by name. That difference is what separates a {{CONDITION}} RazorMax Express from ValueTronics from an unverified marketplace listing or a catalog reseller that never touches the hardware it sells. ## Brand Heritage GaGe is a product brand of DynamicSignals LLC, an ISO 9001:2015 certified company. The brand has been associated with high-speed PC-based digitizer instrumentation for several decades and has carried through successive corporate ownership while retaining the GaGe product identity used on this datasheet. ## Compare Other Models in This Series The RazorMax Express family covers four primary hardware configurations differentiated by channel count and maximum sampling rate. All four models share the same 16-bit vertical resolution, 4 GS (8 GB) of standard onboard dual-port acquisition memory, 50 Ohm SMA inputs, PCIe Gen3 x8 host interface, and identical triggering, clocking, multi-card, and timestamping architectures as described in the datasheet. The differentiators between models are channel count (2 versus 4) and maximum per-channel sampling rate, which in turn sets the analog input bandwidth: 1 GS/s models carry 700 MHz of analog bandwidth and 500 MS/s models carry 350 MHz. Each base model is also available in a low-range (LR) variant with a factory-configured plus or minus 240 millivolt input range in place of the standard plus or minus 1 volt range. Each new RazorMax Express model below is listed on its own product page with condition-matched pricing and an availability status set against the specific unit in our inventory. Selecting the correct model is a function of how many input channels you need to capture simultaneously, the maximum signal frequency you intend to digitize, and whether your input signal levels are better suited to the standard plus or minus 1 volt range or the lower plus or minus 240 millivolt range. The 500 MS/s models (CSE16502 and CSE16504) are specified at 350 MHz analog bandwidth and are well aligned with applications whose signal content is contained within that frequency range. The 1 GS/s models (CSE161G2 and CSE161G4) are specified at 700 MHz analog bandwidth and, per the datasheet, are particularly applicable to RF-based applications that benefit from direct RF sampling of wider band signals. Channel count separates the 2-channel configurations from the 4-channel configurations. Because the standard 4 GS (8 GB) onboard memory is shared and equally divided among active channels, a 2-channel model dedicates more memory per channel during multi-channel capture than the equivalent 4-channel model. The comparison table that follows summarizes the channel count, maximum sampling rate, analog bandwidth, input range option, and memory configuration as printed on the datasheet.

Host system should provide good cooling air flow with ideally an empty adjacent slot to prevent blockage of the card's onboard cooling fan.**Important:** Unless otherwise specified, all dynamic performance specs have been qualified on engineering boards. All specifications are subject to change without notice.Usage tip: for applications that require sustained gap-free recording to disk, the datasheet describes the eXpert PCIe Data Streaming firmware combined with the DsScope and DsScopeView applications for streaming up to 6 GB/s into a Sig-Station class storage system. **Please review the Manufacturer's Data Sheet to verify published specifications.
