USB-1616HS-2 User's Guide Specifications

Note 1: Specifications assume differential input single-channel scan, 1 MHz scan rate, unfiltered, CMV=0.0 V, 30 minute warm-up, exclusive of noise, range is +FS to -FS.

Note 2: Noise reflects 10,000 samples at 1 MHz, typical, differential short.

Thermocouples

Table 3. Thermocouple (TC) types and accuracy (Note 3)

TC type	Temperature range (°C)	Accuracy (±°C)	Noise typical (±°C)
J	-200 to + 760	1.7	0.2
K	-200 to + 1200	1.8	0.2
T	-200 to + 400	1.8	0.2
E	-270 to + 650	1.7	0.2
R	-50 to + 1768	4.8	1.5
S	-50 to + 1768	4.7	1.5
N	-270 to + 1300	2.7	0.3
B	+300 to + 1400	3.0	1.0

Note 3: Assumes 16384 oversampling applied, CMV = 0.0V, 60 minute warm-up, still environment, and 25 °C ambient temperature; excludes thermocouple error; TCin = 0° C for all types except B (1000 °C), TR-2U power supply for external power.

Analog outputs

Analog output channels can be updated synchronously relative to scanned inputs, and clocked from either an internal onboard clock, or an external clock source. Analog outputs can also be updated asynchronously, independent of any other scanning system.
