3.2.6 Frequency reference output (REF OUT)
Use REF OUT to unify the frequency and phase for multiple WF1973, WF1974 units.
Connect the frequency reference output of the master unit when multiple units are
combined in synchronous connection, or the master WF1973 or WF1974, to the external 10
MHz frequency reference input of the WF1973 or WF1974.

■ Output Characteristics
3.2.7 Multi-I/O (MULTI I/O)
MULTI I/O can be used for sweep control and sequence control. It outputs the step
synchronization code for the sequence.
Input frequency 10 MHz (±0.5% (±50 kHz))
Input waveform Sine or square (50 ±5% duty)
Signal GND Insulated from housing and each channel waveform output (42 Vpk max.)
Output voltage 1 Vp-p / 50
Ω
Output impedance 50 Ω , AC coupled
Output frequency 10 MHz
Output waveform Square
Signal GND Same potential as housing

Check
Do not connect any equipment other than the WF1973 and WF1974 not
specified by NF Corporation to the frequency reference output.
The special signal that is output from this terminal during synchronization may
make the operation of such connected equipment unstable.
