Hold

Holds an arbitrary waveform at its current position.ATTL 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 is10kΩ.

ARB Clock In/Out

TGA1210x generators can use an external signal as the arbitrary waveform clock.

The output of this system clock can be made available to drive external circuitry or the input of another generator.

MULTI-CHANNEL OPERATION
Channel Relationships:

The channels of a multi-channel unit can be operated entirely independently, as if they were separate generators. The "copy" key allows the settings of any channel to be instantly copied to another when required. Alternatively, inter-channel relationships of modulation, summing, triggering, or phase locking can be set up.

System Clock: (TGA12102/12104 only)

The TGA12102/12104 units incorporate an additional frequency generator which can be used as a clock source for multi-channel arbitrary waveforms and as an auxiliary output.
	TGA124x	TGA12101	TGA12102/104
Frequency Range:	N/A	N/A	DC to 50MHz.
Frequency Resolution:	N/A	N/A	0·1Hz
The output of the system clock is available as a 1 volt pk-pk sinewave at the Auxiliary Sine Out socket, and as a logic level squarewave at the Ext. ARB In/Out socket. When not being used as a clock source for multi-channel arbitrary waveforms, the system clock provides an independent fixed amplitude sine or square output which is additional to the two or four main channel outputs.

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 channelsmaybe Modulated (AM orSCM)with the signal at theMODULATION input socket.

Carrier waveforms:	All standard and arbitrary waveforms.
Modulation Types:	AM: Double sideband with carrier. SCM: Double sideband suppressed carrier.

Frequency Range:	DC to >100 kHz.
Internal AM Depth:	0% to 105%.
Internal AM Resolution:	1%
Carrier Suppression (SCM):	> 40dB.
External Modulation Signal Range:	VCA: Approximately 1V pk-pk for 100% level change at maximum output. SCM: Approximately ± 1Vpk for max. output.

Multi Channel Sweep

Any number of channels may be swept simultaneously. Amplitude, Offset and Waveform can be set independently for each channel. For TGA124x units the sweep parameters will be the same for all channels. For TGA1210x units the sweep parameters can be set independently for each channel.

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.
	TGA1242/1244	TGA12102/104
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.

External Signal Range:	Approx. 5Vpk-pk input for 20Vpk-pk output.	Approx. 2Vpk-pk input for 20Vpk-pk output.
Input Impedance:	Typically 1 k

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. 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. 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. Different condition apply to Standard waveforms generated using DDS techniques (sine, cosine, haversine, havercosine, triangle, ramps and sinex/x), and those generated using variable clock arbitrary waveform techniques which include square, pulse and pulse train. Arbitrary waveforms and waveform sequences may be phase locked to the Master channel, but certain constraints apply to waveform lengths and clock frequency ratios. On the TGA12102/12104, arbitrary waveforms and waveform sequences can alternatively be clocked from a separate internal clock generator (System clock), or from an external clock input (external ARB clock). When using these clock sources, the restrictions that apply when using the Master channel as the clock source are eliminated. In addition, frequency changes require no settling time to re-establish phase locking, and thus phase continuous frequency changing or sweeping is possible.
