7075 WAVEFORM GENERATOR
SIGNAL SOURCE
Internal Sweep Sequence Functions
Arbitrary Waveform Generator with Four Independently Controllable Channels
The 7075 WAVEFORM GENERATOR includes both function generator and arbitrary waveform generator capabilities. The function generator provides 8 standard waveforms such as sine and square waves. Basic capabilities of the custom waveform generator include long-duration, high-quality waveform output from a 128,000-word memory, 10 MHz clock rate and 16-bit resolution. The function generator and arbitrary waveform output functions can be swept according to various parameters such as frequency and amplitude, making this waveform generator ideal for simulating multiple signal sources for evaluation.

Even for Complex Signals, Evaluation is Made Easy
Features
1. Multiple Channels Four channels (7075) or two channels (7075-01) are provided in a compact, lightweight unit. Multi-channel evaluations such as 3-phase motor simulations can be produced with a single device. 2. Channel-Independent Operation Waveform selection and various settings, including custom waveform sampling clock frequency and sweep control can be set and activated independently for each channel. 3. Simple Operation Simple, direct operation is provided by a touch panel user interface. 4. Easy to Use with Actual Waveforms Waveforms measured with a MEMORY HiCORDER can be downloaded to 3.5" floppy disk or GP-IB. Amplitude and time axes data are downloaded together, so the actual waveforms can be reconstructed. Waveforms and settings can also be saved. The floppy drive is compatible with 1.44-MB MS-DOS format. 5. Synchronized Drive Capability With one unit configured as the master, up to four units (16 channels) can be driven synchronously. 6. Timing Simulation by External Trigger Each channel can be independently triggered by terminals on the rear, so various timings can be simulated. 7. Bundled Waveform Creation Software The bundled 7990 WAVEFORM CREATION SOFTWARE creates waveforms in the Windows TM environment on a PC. Capabilities range from custom waveform design to processing actual waveform simulations. Created waveforms are transferred to the 7075 by floppy disk or RS-232C interface. 8. External Control External control can be provided through the GP-IB interface. Waveforms from a MEMORY HiCORDER can also be downloaded by GP-IB.

Basic Features
q Large 128,000-Word/Channel Memory The large arbitrary waveform memory consists of 128,000 words per channel. Even at the fastest 10 MHz clock, 12.8 ms custom waveforms can be output. q 16-Bit Voltage Axis Resolution, Up to 10 MHz Clock The 16-bit resolution on the voltage axis and 10 MHz maximum clock provide faithful reproduction of actual waveforms and high-quality custom waveform output capability. Three output ranges (0.1, 1 and 10V peak) are provided. q Sweep Sequence Functions Installed Frequency, amplitude and offset can be swept simultaneously, and combinations of sweep conditions in up to 128 steps allow easy generation of complex signals for evaluation. q Eight Basic Waveforms Built In Eight basic waveforms: sine, square, pulse, triangle, ramp up, ramp down, noise and DC are selectable in the function generator mode. Eight waveforms can also be stored in the arbitrary waveform mode, allowing quick handling of all types of waveforms.

7075 Application Functions
q Sweep Sequence Functions Waveform amplitude, frequency, offset and duty cycle* can be swept simultaneously, so multi-pattern signals can be easily generated.
* Duty cycle setting applies only to pulse waveforms. * Table-style entry of up to 128 steps * Settable step loop time * Sequence control by external signals * Long-duration sweep and high-speed data refresh Sweep time of 0.01 ms to 1000 s Maximum data refresh speed of 1 s
Example of simultaneous amplitude and frequency sweep setting
Output waveform example CH1: Simultaneous sweep of amplitude and frequency of a sine wave CH2: Duty cycle sweep of a pulse wave
q Trigger Functions When Hold is enabled for a sequence loop, the Hold can be canceled by the trigger. Specifically, an external trigger can be applied to each channel independently, so variations can be imposed on the output according to custom timing differences between channels. This function is useful in, for example, an automobile ABS simulation in which signals for the four wheels can be controlled independently.
TRIG CH 1 TRIG CH 2 TRIG CH 3 TRIG CH 4
Output controlled by custom timing
Output timing can be controlled by trigger input for each channel at the external control terminals on the rear panel.
q Low-Pass Filter Functions 14 types of low-pass filter with 1-2-5 progression are built in. Device testing capabilities are enhanced by selectably filtering the test signal, such as for noise tests.

q Downloading from a MEMORY HiCORDER Actual measured waveforms saved in a HIOKI MEMORY HiCORDER can be downloaded by floppy disk or GP-IB. All data types are loaded, so the actual measured waveforms are accurately reconstructed. Other data besides the waveform image and amplitude- and timeaxis information is downloaded, so the regeneration process is straightforward. q Converts Text Data to Waveforms Waveforms stored as CSV data can be reconstructed on the 7075. Here is an example of waveform data in Excel TM that was saved as text data, loaded into the 7075 and reconstructed.
