Multifunction output user definable or automatically selected to be any of the following:
Carrier Waveform Sync: The function varies with waveform type as follows:
Sine/Ramp/Pulse - A square wave with 50% duty cycle at the waveform frequency.
Square - A square wave with same duty cycle as the main output at the waveform frequency.
Arbs - A square wave with 50% duty cycle at the waveform frequency. The sync is a TTL high when
the first point of the waveform is output. Noise - No sync associated with noise.
Modulation Sync: The function varies with modulation type as follows:
AM/FM/PM/PWM - A square wave with 50% duty cycle referenced to the internal modulation
waveform when modulation source is internal, or a square wave referenced to the carrier waveform
when modulation source is external. No sync is associated with noise as the modulation source.
FSK - A square wave referenced to the trigger rate. The sync is a TTL high when hop frequency is
the output frequency and TTL low when carrier frequency is the output frequency for positive slope
and vice versa for negative slope. |
| Burst Sync |
A square wave that is a TTL high when the burst begins and a TTL low
when burst is completed. |
| Trigger |
Selects the current trigger signal. Useful for synchronizing burst or
gated signals. |
| Sweep Sync |
The function varies with marker selection as follows: |
Marker Off - A square wave that is a TTL low from the midpoint of the sweep and a TTL high from
the end of the sweep.
Marker On - A square wave that is a TTL low from the marker frequency and a TTL high from the
end of the sweep. |

| TWO CHANNEL OPERATION (TG5012A & TG2512A only) |
| The two channels can be operated independently so as to act as entirely separate generators. Alternatively the channels can interact as follows: |
| Coupled Frequency |
Frequencies can be coupled such that if frequency of one channel is
changed the frequency of the other channel also changes either by a
fixed ratio or fixed offset. A pulse waveforms can only be frequency
coupled to another pulse waveform, however sine, square, ramp or Arb
waveforms can be coupled to any other waveform of that group. |
| Coupled Level |
-Amplitudes (and DC offsets) of the two channels can be coupled such
that changing the amplitude and offset on one channel changes the
amplitude and offset of both channels. |
| Coupled On/Off |
Coupling can be set such that switching the output on/off on one
channel switches the output on/off of both channels. |
When in tracking mode both channels behave as one channel. If inverse tracking is selected,
both channel still behave as one channel except that the output of channel 2 is inverted. |
| Pressing the ‘align’ key phase synchronises the two channels with the specified phase offset. |
| Phase Range |
-360.0 to +360.0 degrees |
| Resolution |
0.1 degree |
| Skew (typical) |
<1ns |
Either channel can be triggered by the other channel to set up a complex and versatile inter
channel trigger scheme.
Each channel can have its trigger output waveform set up independently. Trigger Out may
be selected to be carrier waveform referenced, modulation waveform referenced, sweep
referenced, burst referenced or the currently selected trigger of the channel. |
| Channel Crosstalk |
Typically better than 80dB |
The control of each channel is selected by the Channel Select key.
The display can be assigned either completely to the selected channel, or the upper section
can display the main set-up parameters or waveforms for both channels simultaneously. |
| PHASE SYNC (Phase Synchronising Two Generators) |
Two generators can be synchronised together to provide outputs at the same frequency (or
harmonics) and with a phase difference.
The amplitude and phase of these outputs can also be modulated providing the capability to
perform QAM and QPSK respectively.
In case of 2 channel generators when phase synchronising is performed the two channels of
each generator are also synchronised providing four synchronous waveforms.
It is also possible to synchronise more than two generators but the precision is not
guaranteed. |
