12-bit and 14-Bit Multifunction DAQ Devices MEASUREMENT All devices in this series offer eight singled-ended or four differential analog inputs, two analog outputs, 16 digital I/O, and one counter input. Eight of the digital I/O on the USB-1208FS-Plus/1408FS-Plus can be used for high-current (24 mA) connections. Overview The USB-1208FS-Plus/LS/1408FS-Plus Series consists of low-cost analog and digital I/O devices. All devices in this series offer four differential (DIFF) or eight single-ended (SE) analog inputs, two analog outputs, 16 digital I/O and one event counter. The USB-1208LS offers sample rates up to 1.2 kS/s, while all USB-1208FS-Plus and USB-1408FS-Plus devices (standard and OEM) offer sample rates up to 50 kS/s. All devices in this series also support multiple software-selectable voltage input ranges, making them ideally suited for a wide assortment of measurements.

Analog Input The USB-1208LS and USB-1208FS-Plus provide eight, 11-bit SE analog inputs or four, 12-bit DIFF analog inputs. The USB-1408FS-Plus These devices provide eight, 13-bit SE analog inputs or four, 14-bit DIFF analog inputs. All devices support software-selectable ranges that provide inputs from ±1 V to ±20 V in a DIFF configuration, and ±10 V in a SE configuration. Sample Rate USB-1208LS: When scanning in hardware-paced mode, the USB-1208LS can sample at a maximum of 1.2 kS/s. The device also supports BURSTIO mode into the 4 kS FIFO at rates up to 8 kS/s. USB-1208FS-Plus/1408FS-Plus: In hardware-paced mode, the USB-1208FS-Plus can sample at a maximum of 50 kS/s, and the USB-1408FS-Plus can sample at a maximum of 48 kS/s. Measurement Computing

USB-1208FS-Plus/LS/1408FS-Plus Series Overview Event Counter Input Channel-Gain Queue The channel-gain queue feature lets users configure a list of channels and gains for each scan. Each channel can have a different gain setting. The gain settings are stored in a channel-gain queue list that is written to local memory on the device. Each device supports one 32-bit TTL-level counter that accepts inputs up to 1 MHz. External Clock I/O (-Plus devices only) • The USB-1208LS channel-gain queue list can contain up to eight channels in SE mode and up to four channels in DIFF mode. The channels can...
