DC Accuracy

For the Low-Gain or High-Gain Amplifier Path: 

±0.2% of Amplitude ± 0.05% of Offset ± 500 µV 
(within

±10 °C of self-calibration temperature)

±0.4% of Amplitude 

± 0.05% of Offset ±  1 mV 

(0 °C to 55 °C)

All paths are 
calibrated for 
amplitude and 
gain errors. The 
Low-Gain and 
High-Gain 
Amplifier Paths 
also are 
calibrated for 
offset errors.

For the Direct Path:

Gain Accuracy: 

±0.2% (within ±10 °C of self-calibration 

temperature)

Gain Accuracy: 

±0.4% (0 °C to 55 °C)

DC Error: 

±30 mV (0 °C to 55 °C)

Enable

Software-selectable. When disabled, CH 0 out is terminated 
with a 1 W resistor with a value equal to the selected output 
impedance.

Maximum 
Output 
Overload

The CH 0 output can be connected to a 50

Ω, ±12 V 

(

±8 V for the Direct Path) source without sustaining any 

damage. No damage occurs if the CH 0 output is shorted to 
ground indefinitely.

Waveform 
Summing

The CH 0 output supports waveform summing among 
similar paths—specifically, the outputs of multiple NI 5441 
signal generators can be connected together.
