Cursor/Marker Out
Adjustable output pulse for use as a marker in sweep mode or as a cursor in arbitrary waveform
editing mode. Can be used to modulate the Z-axis of an oscilloscope or be displayed on a second
‘scope channel.
Output Signal Level:
Adjustable from nominally 2V to 14V, normal or inverted; adjustable
width as a cursor.
Output Impedance:
600

Frequency Range:
DC - 1MHz.
Signal Range:
Threshold nominally TTL level; maximum input ±10V.
Minimum Pulse Width:

Tone mode.

Approximately 5Vpk-pk input for 20Vpk-pk output.

Hold
Holds an arbitrary waveform at its current position. A TTL low level or switch closure causes the
waveform to stop at the current position and wait until a TTL high level or switch opening which
allows the waveform to continue. The front panel HOLD key or remote command may also be
used to control the Hold function. While held a rising edge at TRIG IN will return the waveform to
the start. The front panel MAN/SYNC key or remote command may also be used to return the
waveform to the start.

Ref Clock In/Out
Set to Input:
Input for an external 10MHz reference clock. TTL/CMOS threshold
level.
Set to Output:
Buffered version of the internal 10MHz clock. Output levels
nominally 1V and 4V from 50
Ω.
Set to Phase Lock:
Used together with SYNC OUT on a master and the TRIG IN on a
slave to synchronise (phase lock) multiple instruments.
