• Interpolation set to maximum allowed factor for a given sample rate. • Signals terminated with 50 .. • Direct Path set to 1 Vpk-pk, Low-Gain Amplifier Path set to 2 Vpk-pk, and High-Gain Amplifier Path set to 12 Vpk-pk. • Sample clock set to 100 MS/s. Typical values are representative of an average unit operating at room temperature. Specifications are subject to change without notice. For the most recent NI 5421 specifications, visit ni.com/manuals. To access all the NI 5421 documentation, including the NI Signal Generators Getting Started Guide, which contains functional descriptions of the NI 5421 signals, navigate to Start»Programs»National Instruments»NI-FGEN»Documentation. Hot Surface If the NI 5421 has been in use, it may exceed safe handling temperatures and cause burns. Allow the NI 5421 to cool before removing it from the chassis.

Specification Value Comments Number of Channels 1 — Connector SMB (jack) — Output Voltage Characteristics Output Paths 1. The software-selectable Main Output Path setting provides full-scale voltages from 12.00 Vpk-pk to 5.64 mVpk-pk into a 50 . load. NI-FGEN uses either the Low-Gain Amplifier or the High-Gain Amplifier when the Main Output Path is selected, depending on the Gain attribute. 2. The software-selectable Direct Path is optimized for IF applications and provides full-scale voltages from 1.000 Vpk-pk to 0.707 Vpk-pk. — DAC Resolution 16 bits — NI 5421 Specifications 2 ni.com Table 1. (Continued) Table 1. (Continued) Value Comments Amplitude and Offset Amplitude Range Path Load Amplitude (Vpk-pk) 1. Amplitude values assume the full scale of the DAC is utilized. If an amplitude smaller than the minimum value is desired, then waveforms less than full scale of the DAC can be used. 2. NI-FGEN compensates for user- specified resistive loads.
