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 MAN HOLD key or remote command may also be used to control the Hold function. While held the front panel MAN TRIG key or remote command may be used to return the waveform to the start. The Hold input may be enabled independently for each channel.

Input impedance

Inter-Channel Operation

Inter-Channel Modulation

The waveform from any channel may be used to Amplitude Modulate （AM） or Suppressed Carrier Modulate （SCM） the next channel. Alternatively any number of channels may be Modulated （AM or SCM） with the signal at the MODULATION input socket.

Carrier frequency

Entire range for selected waveform

Carrier waveforms

All standard and arbitrary waveforms

Modulation types: AM

Double sideband with carrier. SCM: Double sideband suppressed carrier

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

0 % to 105 %.

Carrier suppression （SCM）

> 40 dB

External modulation signal range

Inter-Channel Analogue 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 > 8 MHz

Ext. signal range

Approx. 5 V pk-pk input for 20 V pk-pk output

Inter-Channel Phase Locking

Two or more channels may be phase locked together. Each locked channel may be assigned a phase angle relative to the other locked channels. Arbitrary waveforms and waveform sequences may be phase locked 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 multiphase waveforms at the same frequency to be easily generated. DDS waveforms are those with 7 digits of frequency setting resolution, while Non-DDS waveforms have 4 digits.

Phase resolution Non-DDS waveforms

DDS waveforms: 0.1 degree or 360 degrees/number of points whichever is the greater

Phase error

	< ± 10 ns all waveforms
	The signals from the REF IN/OUT socket and the SYNC OUT socket can be used to phase lock two instruments where more than 4 channels are required.

Inter-Channel Triggering

Any channel can be triggered by the previous or next channel. The previous/next connections can be used to ‘daisy chain’ a trigger signal from a ‘start’ channel, through a number of channels in the ‘chain’ to an ‘end’ channel. Each channel receives the trigger out signal from the previous （or next） channel, and drives its selected trigger out to the next （or previous） channel.
The ‘end’ channel trigger out can be set up to drive the ‘start’ channel, closing the loop. In this way, complex and versatile interchannel trigger schemes may be set up. Each channel can have its trigger out and its output waveform set up independently. Trigger out may be selected from Waveform End, Position Markers, Sequence Sync or Burst Done.
Using the scheme above it is possible to create a sequence of up to 64 waveform segments, each channel producing up to 16 segments and all channels being summed to produce the complete waveform at the output of channel 4.
