You can multiply the frequency by the WCM (wave cycle multiplier) which is the # found in the Settings Tab besides the waveform selected. In this case, the WCM is 16. This will be the output on the Generator. It is normal. Only when you choose waveform with a WCM of 1 (like square wave) would the frequency be the same on the Generator itself.
