8.6 Options
z 1991 synchronous operation option
Function
Time difference
Others
Synchronous operation of multiple units of the WF 19 series*
1991 is required all synchronous operation.
Under condition of continuous oscillations, external AM off, 50
Ω load,
DC offset 0 V and amplitude setting 10 Vp-p/50
Ω, phase synchronization
after setting same waveform and frequency,
The time difference among the equipment: (
±25 ns + 10 ns/unit) and below.
The cable connecting multiple units of the WF 19 series* is optional.
(1994 synchronous operation cable)
z 1994 synchronous operation cable
1991 synchronous operation option, for connecting multiple units of the WF 19 series*. To
connect n units of the WF 19 series* (n
−1) of 1994 synchronous operation cables are necessary.
z 1992A digital output option
Function
Data format
Output digital signal applied to waveform D/A.
Upper 15 bits of the 16-bit waveform data and the clock are output.
The relation between arbitrary waveform data setting and output data is as
follows :
