Arbitrary waveforms can be defined by downloading of waveform data via RS232 or USB (or GPIB if fitted) Waveform Size: 65536 (64K) points maximum, 8 points minimum. Vertical Resolution: 12 bits Sample Clock Range: 100mHz to 100MHz. Resolution 7 digits or 0.1 mHz Output Filter: Selectable between 40MHz Elliptic, 20MHz Bessel or none. Noise Function: Digital noise generated by a 35-bit linear feedback register clocked at 100MHz. User?s external filter defines bandwidth and response. ARBITRARY WAVEFORM CREATION / EDITING Waveform Manager Plus software for Windows is supplied. Full details of its capabilities are on our website or within the Waveform Manager Plus brochure. MODULATION MODES Sweep Capability provided for both standard and arbitrary waveforms. Arbitrary waveforms are expanded or condensed to exactly 4096 points and DDS techniques are used to perform the sweep. Carrier Waveforms: All standard and arbitrary except pulse and pulse train. Sweep Mode: Linear or logarithmic, continuous or triggered. Sweep Direction: Up, down, up/down or down/up. Sweep Range: 1mHz to 40 MHz in one range. Phase continuous. Independent setting of start/stop. Sweep Time: 1ms to 999s (3 digit resolution). Marker: Variable during sweep. Sweep Trig. Source: The sweep may be free run or triggered from the following sources: Manually from keyboard. Externally from TRIG IN input or remote interface. Triggered Burst Each active edge of the trigger signal will produce one burst of the waveform. Carrier Waveforms: All standard and arbitrary. Max.Carrier Freq.: The smaller of 2.5MHz or the maximum for the selected waveform. 100Msamples/s for ARB. Number of Cycles: 1 to Trigger Repitition Rate: 0.005Hz to 100kHz internal, dc to 1MHz external. Trigger Source: Internal from keyboard or trigger generator. External from TRIG IN or remote interface. Start/Stop Phase: ? 360? settable with 0.1? resolution, subject to waveform frequency and type. Gated Waveform will run while the Gate signal is true and stop while false. Carrier Waveforms: All standard and arbitrary. Max.Carrier Freqy.: The smaller of 2.5MHz or the maximum for the selected waveform. 100Msamples/s for ARB. Trigger Rate: 0.005Hz to 100kHz internal, dc to 1MHz external. Gate Signal Source: Internal from keyboard or trigger generator. External from TRIG IN or remote interface. Start/Stop Phase: ? 360? settable with 0.1? resolution, subject to waveform frequency and type. Tone Switching Carrier Waveforms: All waveforms except pulse and pulse train. Frequency List: Up to 16 frequencies from 1mHz to 40MHz. Trigger Repitition Rate: 0.005Hz to 100kHz internal, dc to 1MHz external. Usable repetition rate and waveform frequency depend on the tone switching mode. Source: Internal from keyboard or trigger generator. External from TRIG IN or remote interface. Tone Switching Modes: Gated: The tone is output while the trigger signal is true and stopped, at the end of the current waveform cycle, while the trigger signal is false. The next tone is output when the trigger signal is true again. Triggered: The tone is output when the trigger signal goes true and the next tone is output, at the end of the current waveform cycle, when the trigger signal goes true again. FSK: The tone is output when the trigger signal goes true and the next tone is output, immediately, when the trigger signal goes true again. Using 2 instruments with their outputs summed together it is possible to generate DTMF test signals. Trigger Generator Internal source 0.005 Hz to 100kHz squarewave adjustable in 10us steps. 3 digit resolution.

Sync Out Multifunction output user definable or automatically selected to be any of the following: Waveform Sync: (all waveforms) A square wave with 50% duty cycle at the main waveform frequency, or a pulse coincident with the first few points of an arbitrary waveform. Burst Done: Produces a pulse coincident with the last cycle of a burst. Trigger: Selects the current trigger signal. Useful for synchronising burst or gated signals. Sweep Sync: Outputs a pulse at the start of sweep to synchronise an oscilloscope or recorder. Sweep Marker: Additional output pulse for use as a marker in sweep mode. Can be used to modulate the Z-axis of an oscilloscope or be displayed on a second 'scope channel. Phase Lock Out: Used to phase lock two or more generators. Produces a positive edge at the 0o phase point. Output Signal Level: Logic levels of <0.8V & >3V, except for Sweep Sync. Sweep Sync is a 3-level waveform: low at start of sweep, high for the duration of the last frequency step at end of sweep, with a narrow 1V pulse at the marker point.
