CH1/2 Settings

Synchronize

Our instruments can output basic waveforms (except noise), arbitrary waveforms (except DC), harmonics, sweep waveforms, burst waveforms, and synchronized waveforms of modulated waveforms from a single channel or simultaneously from

4.Panel Operation

two channels. This signal is output from the front panel [Sync] connector.

(1) Sync Switch

Enable or disable the sync signal on the [Sync] connector. Press Utility to set CH1

sync/CH2 sync and select “On” or “Off” sync signal output. The default is "on", which sends the sync signal to the [Sync] connector. The output level on the [Sync] connector is a logic low when the sync signal is turned off.

(2) Synchronization signal of various waveforms

 For sine, square, ramp and pulse waves, the sync signal is a square wave with a 50%

duty cycle. When the waveform output is positive, the sync signal is TTL high with

respect to the 0V voltage (or DC offset value). When the waveform output is negative,

the sync signal is TTL low relative to the 0V voltage (or DC offset value).

 For an arbitrary waveform, the sync signal is a square wave with a variable duty cycle.

When the output waveform amplitude reaches a certain value, the sync signal is TTL

high.

 For harmonics, the sync signal is referenced to the harmonic order and is a square wave

with a variable duty cycle. When the output waveform amplitude is positive, the sync

signal is TTL high.

 For AM, FM, PM, and PWM, for internal modulation, the sync signal is referenced to

the modulation frequency, and the sync signal is a square wave with a 50% duty cycle.

In the first half of the modulation waveform, the sync signal is TTL high. When external

modulation is performed, there is no sync signal output.

 For ASK, FSK, PSK, BPSK, 3FSK, 4FSK, the synchronization signal is referenced to the

keying frequency, and the synchronization signal is a square wave with a duty cycle of

50%. There is no sync signal output during external modulation.

 For OSK, the sync signal is referenced to the keyed frequency and the sync signal is a

square wave with a 50% duty cycle. When the internal crystal oscillator starts, the sync

signal is TTL high.

 For N-cycle bursts, the sync signal is TTL high at the beginning of the burst. At the end

of the specified number of cycles, the sync signal is TTL low (if the waveform has an

associated start phase, it may not be a zero crossing). For an infinite count pulse train,

the sync signal is the same as the sync signal of the continuous waveform.

 For external gated bursts, the sync signal follows its gate signal. Note: This signal does

not become TTL low until the end of the last cycle (if the waveform has an associated

starting phase, it may not be a zero crossing).

Output Setting
