| Modulation Modes |
| Triggered burst |
Each active edge of the trigger signal will produce one burst of the carrier waveform, waveforms starts from point n and completes at point n-1 |
| Gated |
The selected waveform is output continuously at the programmed frequency while the selected gate signal is true |
| Waveforms |
All standard and arbitrary |
| Carrier frequency |
125 Msample/s for ARB and Sequence. 2.5 MHz or the maximum of selected waveform |
| No. of cycles |
1 to 1,000,000 |
| Trigger source |
Manual trigger key, adjacent channel or internal trigger generator or external trigger input or remote trigger command |
| Trigger rate |
Internal trigger generator: 0.1 Hz to 2 MHz; External signal: dc to 2 MHz |
| Start/stop phase |
± 360 ° , settable to 0.1 ° subject to waveform frequency and type |
| Frequency sweep |
Manual, continuous, triggered; linear or logarithmic sweep; up or down. Variable sweep marker. |
| Sweep range |
1 mHz to 125 MHz |
| Sweep time |
1 ms to 999 s |
| Sweep trigger source |
External trigger input or remote trigger command |
| Tone switching |

| External AM |
Via rear panel BNC input, dc-500 kHz for all standard and arbitrary waveforms |
|
| Outputs and Inputs |
| Main outputs |
|
| Sync outputs |
| |
Front panel BNC connector generates sync pulse synchronous with output waveform. In FM and sweep modes this output is synchronous with sample clock frequencies |
|
| Ext. trigger |

|
| AM input |
| |

|
| Ref clock in |
| |
Input for an external 10 MHz reference clock. Threshold nominally TTL level. |
|
| SCLK output, SCLK input and DSUB connector |
| |
Connect instruments to achieve synchronization. DSUB 9- pin connector and 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. |
