USB-200 Series

Both USB-200 Series devices provide eight single-ended (SE) analog inputs, eight individually-configurable DIO channels, one event counter, and external pacer I/O. Everything you need to begin acquiring, viewing, and storing data is included with these devices, including comprehensive software support.

Analog Input
USB-200 Series devices provide eight 12-bit SE analog inputs. Both devices offer an analog input range of ±10 V.

Sampling Rate
When scanning continuously to computer memory (hardware-paced mode), each device has the following maximum aggregate sampling rates:

USB-201: 100 kS/s

USB-204: 500 kS/s

Channel Queue
The channel queue feature lets you configure a list of unique ascending channel configuration for each scan. The channel settings are stored in a channel queue list that is written to local memory on the device.

External Pacer I/O
Each USB-200 Series device provides one external clock input and one clock output for the analog input pacer. You can connect an external clock signal to the external clock input terminal. When using the internal clock, each device outputs the ADC sample clock.

Digital I/O
USB-200 Series devices provide eight TTL-level digital I/O lines. Each digital channel is software-selectable for input or output. When configured for input, you can use the digital I/O terminals to detect the state of any TTL-level input.

Pull-Up/Pull-Down Configuration
Each USB-200 Series device has a user-configurable internal jumper to configure the digital bits for pull-up or pull-down (default).

Event Counter Input
Both devices support one 32-bit TTL-level event counter that accepts inputs up to 1 MHz.
