Outputs Inputs
Main outputs	397:00:00 Two channel
Sync outputs	Front panel BNC connector generates sync pulse synonous with output waveform. In FM sweep modes this output is synonous with sample clock frequencies
Ext. trigger	DC to 2 MHz. Threshold nominally TTL level; maximum input 5 V. Selectable as positive rising edge or negative falling edge. Minimum pulse width 20 ns for trigger gated modes
AM input	0 V to +5 V (5 Vpp) produce 100 % modulation
Ref clock in	Input for an external 10 MHz reference clock. Threshold nominally TTL level.
SCLK output, SCLK input DSUB connector	Connect instruments to achieve synonization. DSUB 9- pin connector cable supplied.

Inter-Channel Operation
Inter-channel modulation	The waveform from any channel may be used to amplitude modulate (AM) the adjacent instrument/channel. Alternatively, any number of channels may be modulated (AM) with the signal at the modulation input socket.
Carrier frequency	Entire range for selected waveform
Carrier waveforms	All stard arbitrary waveforms
Modulation freq.	DC to 500 kHz
Modulation depth	0 % to 100 %
Inter-channel synonization	397:00:00 Both channels are tightly synonized in phase waveform start. Channel 2 has sample clock divider for arbitrary sequenced waveforms.
Phase resolution	397:00:00 1 sample clock period of channel 2
Skew error	397:00:00 ± 2 ns
Inter-instrument synonization	Two or more instrument may be slaved to one instrument. Each Slave can have a unique phase resolution relative to the Master.
Phase error	4 points
Skew error	+/-20ns Typically with 20c"m coax cable
