Protect Function. Protects (makes read-only) a section of waveform memory.
F1: FROM - Selects the address of the first point to protect.
F2: TO - Selects the address of the last point to protect.
F3: ALL - Protects the whole waveform memory. Equivalent to selecting from 1 to 4,000,000.
Note: You can protect only one segment of waveform memory at a time.
F4: ON/OFF - Selects the unprotect mode and resets memory protection so that the whole waveform
memory can be written into.
F5: PREV - Returns to previous menu.
3.6.5 PULSE Menu
From the WAVE menu, select F4:PULSE.
F1: FREQ/PERIOD - Selects the parameter definition of the Pulse repetition period.
F2: WIDTH - Selects the Width of the generated pulse.
F3: EQUAL EDGE - Selects equal Rise (Leading edge) and Fall (Trailing edge) times of the pulse.
F4: LEAD-TRAIL - Selects different Rise and Fall times of the Pulse.
F5:PREV - Returns to previous menu.
3.6.6 UTILITY Key
Utility Menu
F1: GPIB - Selects the GPIB remote mode of operation. After selection the GPIB address can be set to any value
from 1 to 31 using the rotary knob. The value is kept in a nonvolatile memory and used at power-on. The
factory default address is 9. Setting the address to 31 puts the device in the off-bus state (it will not respond
to messages on the GPIB bus).
F2:RS232 - Selects the RS232 remote control mode. After selection, the baud rate can be selected as 2400, 9600,
19200, and 38400. The RS-232 uses 8 bit data, 1 stop bit and no parity.
