Accuracy
DC Accuracy For the Low-Gain or High-Gain Amplifier Path:
±0.2% of Amplitude ± 0.05% of Offset ± 500µ V
(within ±10 °C of self-calibration temperature)
±0.4% of Amplitude ± 0.05% of Offset ± 1mV
(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)
AC Amplitude
Accuracy
±1.0% of Amplitude ± 1mV 50 kHz sine
wave.

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.
