Amprobe Test Tools Arbitrary Waveform Generator 195

The 195 is a 16 MHz arbitrary waveform generator from WaveTek. An arbitrary waveform generator (AWG) is a type of electronic test equipment people use to generate repetitive or single-shot electrical waveforms. Single-shot waveforms require a triggering source, either internal or external, while repetitive waveforms do not. Inject the signal the waveform generator creates into a device for analysis during testing, finding problems with the device, or confirming proper operation. Features: Waveforms Standard Waveforms Sine, square, triangle, DC, positive ramp, negative ramp, sin(x)/x, pulse, pulse train, cosine, haversine and havercosine.

DC offset plus signal peak limited to +/-10V from 50ω DC Offset Accuracy: Typically 3% +/-10mV, unattenuated Resolution: 3 digits or 1mV for both Amplitude and DC Offset Sync Out - One for each channel Multifunction output user definable or automatically selected to be any of the following: Waveform Sync: A square wave with 50% duty (all waveforms) cycle at the main waveform frequency, or a pulse coincident with the start of an arbitrary waveform. Position Markers: Any point(s) on the waveform (arbitrary only) may have associated marker bit(s) set high or low. Burst Done: Produces a pulse coincident with the last cycle of a burst. Sequence Sync: Produces a pulse coincident with the end of a waveform sequence. Trigger: Selects the current trigger signal. Sweep Sync: Outputs a pulse at the start of sweep to synchronize an oscilloscope or recorder. Phase Lock Out: Used to phase lock two generators. Produces a positive edge at the 0° phase point. Output Signal Level: TTL/CMOS logic levels from typically 50ω Cursor/Marker Out Adjustable output pulse for use as a marker in sweep mode or as a cursor in arbitrary waveform editing mode. Can be used to modulate the Z-axis of an oscilloscope or be displayed on a second scope channel. Output Signal Level: Adjustable from nominally 2V to 14V, normal or inverted; adjustable width as a cursor. Output Impedance: 600ω typical Inputs Trig In Frequency Range: DC-1MHz. Signal Range: Threshold nominally TTL Level: maximum input +/-10V. Minimum Pulse Width: 50ns, for Trigger and Gate modes; 50us for Sweep mode.

Signal Range: 1V for 100% level change at maximum output Input Impedance: Typically 1kω Sum In Frequency Range: DC - 8MHz. Signal Range: Approximately 2Vpk-pk input for 20Vpk-pk output. Input Impedance: Typically 1kW. Hold Holds an arbitrary waveform at its current position. A TTL 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 HOLD key or remote command may also be used to control the Hold function. Input Impedance: 10ω Ref Clock In/Out Set to Input: Input for an external 10MHz reference clock. TTL/CMOS threshold level. Set to Output: Buffered version of the internal 10MHz clock. Output levels nominally 1V and 4V from 50ω Inter-channel operation 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 channels may be Modulated (AM or SCM) with the signal at the MODULATION input socket. Carrier frequency: Entire range for selected waveform. Carrier waveforms: All standard and arbitrary waveforms. Modulation Types AM: Double sideband with carrier. SCM: Double sideband suppressed carrier. Modulation source: Internal or External Frequency Range: DC to >100 kHz. Internal AM: Depth: 0% to 105% Resolution: 1%. Carrier Suppression (SCM): > -40dB. External Modulation Signal Range: Approximately 1V pk-pk for 100% level change at maximum output. Inter-channel Analog 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. Carrier frequency: Entire range for selected waveform. Carrier waveforms: All standard and arbitrary waveforms. Sum source: Internal or External Frequency Range: DC to 8MHz. External Signal Range: Approximately 5Vpk-pk input for 20Vpk-pk output. Inter-channel Phase locking Two or more channels may be phase locked together. One channel is assigned as the Master and the other channels as Slaves. Each Slave can have a phase angle relative to the Master. Arbitrary waveforms and waveform sequences may be phase locked but certain constraints apply to waveform lengths and clock frequency ratios. Phase Resolution DDS waveforms: 0.1° Non-DDS waveforms: 0.1° or 360°/ number of points whichever is the greater. Phase Error All waveforms: <+/-10ns The signals from the REF IN/OUT socket and the SYNC OUT socket can be used to phase lock two instruments. Inter-channel Triggering Any channel can be triggered by the previous or next channel. The previous/next connections can be used to ‘daisy chain’ a trigger signal from a ‘start’ channel, through any number of channels to an ‘end’ channel. In this way, complex and versatile inter-channel trigger schemes may be set up. Each channel can have its trigger out and its output waveform set up independently. Trigger out may be selected from Waveform End, Position Markers, Sequence Sync or Burst Done. Using this scheme, it is possible to create a sequence of up to 64 waveform segments, each channel producing up to 16 segments and all channels being summed to produce the complete waveform at the output of channel 4. Interfaces Full remote control facilities are available through the RS232 or GPIB interfaces. RS232: Variable Baud rate, 9600 Baud maximum. 9-pin D-connector.

The Wavetek 195 Universal Waveform Generator has sophisticated capabilities that make generating complex signals easy and convenient. Combining synthesized performance with 2 or 4 independent 40 MS/s channels, the 195 is a powerful test tool for a wide variety of applications. The 195 uses a combination of direct digital synthesis, phase lock loop techniques and innovative firmware to provide high performance and extensive facilities in a compact instrument. The 195 provides sine and square waves up to 16 MHz.
