This product is grounded automatically by connecting a three-pin power supply plug to a power
supply outlet with a protective earth contact.
Check the power supply voltage.
This product operates on the power supply voltage indicated in section “2.3 Grounding and
Power Supply Connection” in this instruction manual.
Prior to connecting the power supply, check that the outlet voltage matches the rated power
voltage of the product.
If you suspect a problem
If this product emits smoke, a strange odor, or an unusual sound, immediately pull the power
cable and stop using it.
If such an abnormality occurs, do not let anyone use this product until it has been repaired, and
immediately report the problem to NF Corporation or one of our representatives.

10MHz External Frequency Reference
Maximum Output Voltage: 20Vp-p/open (10Vp-p/50Ω, 110MHz or less), 4Vp-p/open
(2Vp-p/50Ω, 110MHz to 200MHz), Minimum Output Voltage: 0V (Can reach 0 using
Amplitude control)
Standard Waveforms with Multivariable Parameters: Sine wave, Square wave (variable duty),
Pulse (variable pulse width/duty, rising time, falling time), Ramp wave (variable symmetry),
CF control Sine wave (variable crest factor), Staircase Sine wave (variable step number),
