reference when an adequate signal level (TTL/CMOS threshold) is detected at REF CLOCK
IN/OUT but will continue to run from the internal clock in the absence of such a signal.
With the clock set to
output
a buffered version of the internal 10MHz clock is made available at
the socket.
With
phase lock
selected the socket can be set to be a
master
or
slave
when used
for
synchronising (phase-locking) multiple generators. See Synchronising Generators section for full
details.
Remote Interface Setup
Pressing
remote…
calls the
REMOTE SETUP
screen which permits RS232/GPIB choice and
selection of address and Baud rate. Full details are given in the Remote Operation section.
Cursor/Marker Output
Pressing the
cursor/marker…
soft-key calls the
CURSOR/MARKER OUTPUT
screen.
CURSOR/MARKER OUTPUT
amplitude: 2V
◊
polarity: negative
◊
cursor width: 1
The cursor/marker signal is output from the rear panel CURSOR/MARKER OUT socket. It is used
as a marker in sweep mode or as a cursor in arbitrary waveform mode. It can be used to
modulate the Z-axis of an oscilloscope or be displayed on a second ‘scope channel.
With
amplitude
selected the cursor/marker level can be set between 2 and 14V in 2V steps.
With
polarity
selected the polarity can be set
positive
or
negative
. With
polarity
set to
positive
the cursor/marker is a positive-going pulse from the 0V baseline; with
polarity
set to
negative
the cursor/marker is a negative-going pulse from the 2 - 14V set
amplitude level, i.e.
negative
gives an inverted signal.
When used as a sweep marker (i.e. Sweep mode selected) the width is determined by the time
spent at the marker frequency, see Sweep Marker in the Sweep Operation section for details.
When used as a cursor during arbitrary waveform editing (i.e.
edit waveform
selected on
the
MODIFY
screen) the width can be adjusted by repeated presses of the
cursor width
soft-key
or by using the rotary control. The width is adjustable so that the cursor can still be made visible
even with long arbitrary waveforms. The width is always an odd number of waveform points
increasing in steps of 2 points from 1 to 3, 5, 7, etc. A
width
setting of 1 corresponds to 1
waveform point,
width 2
is 3 points,
width 3
is 5 points and so on up to
width 30
which
is 59 points.
