Modulation source: Internal from the previous channel;
external from modulation input socket.
The external modulation signal may be applied to any
number of channels simultaneously.
Frequency range: DC to >100 kHz.
Internal AM:
depth:
resolution:
0 % to 105 %
1 %.
Carrier suppression (SCM): >40 dB.
External modulation signal
range: VCA:
SCM:
Approximately 1 V p-p for 100 % level change at
maximum output.
Approximately ±1 V pk for maximum output.
Inter-Channel Analog Summing:
Waveform summing sums the waveform from any channel into the next channel.
Alternatively any number of channels may be summed with the signal at the
SUM input
socket.
Carrier frequency: Entire range for selected waveform.
Carrier waveforms: All standard and arbitrary waveforms.
Sum source: Internal from the previous channel;
external from
SUM IN socket.
Frequency range: DC to >25 MHz.
External signal range: Approximately 5 V p-p input for 20 V p-p output.
Inter-Channel Synchronization:
Two or more channels may be synchronized together. Each synchronized channel may
be assigned a phase angle relative to the other locked channels. Arbitrary waveforms and
waveform sequences may be synchronized but certain constraints apply to waveform
lengths and clock frequency ratios. With one channel assigned as the master and other
channels as slaves a frequency change on the master will be repeated on each slave thus
allowing easy generation of multi-phase waveforms at the same frequency.
Channels may be clocked using the master channel, the system clock or an external arb
clock.
Phase resolution:
DDS waveforms:
non-DDS waveforms:
0.1 degree
0.1 degree or 360 degrees divided by the number of
points, whichever is the greater.
Phase error:
all waveforms: <±6 ns (internal clock),
<±5 ns (external arb or system clock)
The signals from the
REF IN/OUT socket and the SYNC OUT socket can be used to
phase lock two instruments where more than four channels are required.
Inter-Channel Triggering:
Any channel can be triggered by the previous or next channel.
