MAIN OUT (1 per channel)
MAIN OUT is the 50 Ω output from the channel's main generator. It will provide up to
20 V p-p into an open circuit or 10 V p-p into a matched 50 Ω load. It can tolerate a
short circuit for 60 seconds.
Caution
Do not apply an external voltage to this output.
SYNC OUT (1 per channel)
SYNC OUT is a TTL/CMOS level output which may be set to any of the following
signals from the
SYNC OUT screen.
waveform sync A sync marker phase coincident with the MAIN OUT
waveform. For standard waveforms, (sine, cosine, haversine,
havercosine, square, triangle, sin(x)/x and ramp), the sync
marker is a square wave with a 1:1 duty cycle. The rising edge
is at the 0 º phase point and the falling edge at the 180 º phase
point. For arbitrary waveforms the sync marker is a positive
pulse coincident with the first few points (addresses) of the
waveform.
position marker When position (pos’n) marker is selected, the instrument
generates a pulse marker pattern for arbitrary waveforms. The
pulse pattern is programmable from the
edit waveform
menu on the MODIFY screen.
Burst done Provides a signal during gate or trigger modes which is low
while the waveform is active at the main output and high at all
other times.
Sequence sync Provides a signal which is low during the last cycle of the last
waveform in a sequence and high at all other times.
Trigger Provides a positive-going version of the actual trigger signal;
internal, external, manual and remote all produce a trigger sync.
Sweep sync Goes high at the start of sweep and remains high for the
duration of the first frequency step. In addition, a half-
amplitude marker pulse can be set to be output at any of the
frequency steps.
Phase lock Produces a positive edge coincident with the start of the current
waveform; this is used for phase locking instruments. This
waveform may not appear coherent.
SYNC OUT logic levels are nominally 0 V and 5 V from typically 50 Ω. SYNC OUT
will withstand a short circuit.
Caution
Do not apply an external voltage to this output.
