8. One last vector exists in the waveform. Press V MKR to display the number of
tor 12. Turn the Modify knob to display Vector 13. This is the Return to Start
tor which corresponds to the SYNC signal's negative
the Start/Finish point and remains there until the ARB wave begins the next period.
The V LEN is modifiable, but not the V HGT.
To change the waveform characteristics, adjust FREQ, AMPTD, and OFFSET. Ad-
justing PHASE will distort the waveform. Modifying other ENTRY parameters is not
allowed.
It is easiest to build a waveform at maximum amplitude and frequency for ease of
viewing, then change it as needed. To select individual vectors, press V MKR then
dial to the desired vector. Modify V HGT and V LEN as
Recalling an ARB Waveform
The ARB key and the

ARx" (x
0 through 5) will be displayed for
the active ARB wave. Pressing RCL, ARB, and then one of register 0 through 5 ("RWO"
through "RW5" HP-IB commands) recalls one of six ARB waves.
Though you may store standard waveforms to specific registers after defining the
parameters, ARB waveforms are simultaneously built and stored in the register of your
choice in non-volatile memory. Even if power is lost, the wave parameters remain in-
tact. Simply recall the ARB wave function to restore the output signal.
