Overview
1.1 Product Overview
The 7075 is a multi-channel waveform generator with function generator and
arbitrary wavefor m generator function. The function generator provides eight
basic waveform types, such as sine and square waves. The arbitrary
waveform output allows generating long-duration, high-quality waveforms.
Basic capabilities include 128,000-word-long memory, 10-MHz clock rate
and 16-bit resolution.
The function generator and arbitrary waveform output can be swept
according to each wavef orm parameter, so this waveform generator is ideal
for sim ulating a variety of signal sources and test situations.
A large LCD with touch panel provides very easy operation.

Jog Dial Entry
The Jog dial can be used to set frequency or clock frequency. When a
arbitrary waveform is selected, the clock frequency is displayed at the left
side and the output frequency can be set within parentheses.
Setting is inhibited when sweep is active
Setting is inhibited for noise or DC waveforms
All settings are stored as frequencies within the 7075. Because rpm (r/min)
and period (s) formats are converted to facilitate the internal analysis
functions, entered values and actual setting values may differ slightly, in
which case the actual setting is made as close as possible to the entered
value.
When changing a waveform, if the setting frequency exceeds the settable
range of that waveform, the maximum allowable value is used.
The Jog dial can be used to set frequency and clock frequency formats, but
not the rpm (r/min) or period (s) formats.

3.4.2 Amplitude/Upper Limit Value Settings
Set the amplitude or upper limit value of the output waveform.
Setting range Regardless of the output waveform, the settings can be made in the
following range.
When setting the amplitude
10V range 0 to 10 Vp (resolution 1 mVp)
1V range 0 to 1 Vp (resolution 0.1 mVp)
0.1V range 0 to 0.1 Vp (resolution 0.01 mVp)
When setting the upper limit value
10V range Lower limit value to 10 V (resolution 2 mV)
1V range Lower limit value to 1 V (resolution 0.2 mV)
0.1V range Lower limit value to 0.1 V (resolution 0.02 mV)
Setting units
Method
Vp
For amplitude setting, sets the amplitude of one polarity
Vpp
For amplitude setting, sets peak-to-peak amplitude
V
For amplitude setting, sets the root-mean-square amplitude (only for
RMS
sine waves)
V
Sets the voltage when setting the upper limit
Direct Entry
1. Press the Amplitude/Upper limit setting button (
AMPL/UPPER
) to open the
AMPL/UPPER Settings window.
2. Select either amplitude or upper limit entry format.
3. Enter the numeric value by the tenkeys.
4. Select the units. Pressing the unit button accepts the value entered in step 3,
and returns to the main Output settings screen. The main screen shows the
entered format, or if the setting is invalid, the entry is cleared.

Jog Dial Entry
The Jog dial can be used to set amplitude or upper limit value.
NOTE
Setting is inhibited for DC waveforms
Amplitude/offset and upper/lower limit settings are interdependent: a change
to the setting format of one item is automatically applied to the other.
Amplitude --- upper limit
Offset --- lower limit
The output voltage range is the setting at high-impedance load.
The sum of the peak amplitude and the absolute value of the offset is
limited to the set range. Overrange setting is not possible.
The RMS amplitude unit selection is automatically changed to Vp units if
the waveform selection is changed.
3.4.3 Offset/Lower Limit Value Settings
Set the offset voltage or lower limit value of the output waveform.
Setting range
Offset
10 V range -10 V to 10 V (resolution 1 mV)
1 V range -1 V to 1 V (resolution 0.1 mV)
0.1 V range -0.1 V to 0.1 V (resolution 0.01 mV)
Lower limit value
10 V range -10 V to upper limit value (resolution 2 mV)
1 V range -1 V to upper limit value (resolution 0.2 mV)
0.1 V range -0.1 V to upper limit value (resolution 0.02 mV)
Setting unit V: Set the voltage value
