It seems that when setting the Ni 5402 Sig Gen's frequency from one value to the next using its standard function mode (sinewave, typically 5000Hz, ivi), the output momentarily switches off/on.

This switching appears as a glitch on the output which is enough to cause havoc with my test item. I have used other makes of Signal Generator before and not had this problem.

Is there a way of reducing the output glitches of the Ni 5402 signal generator or is it just a nasty signal generator?

Sweep mode does not give glitches when sweeping but still gives glitches when switching between sweep & standard function modes (as the output momentarily switches off/on).
