3. Important inputs for synthesizer
The following elements can have a big impact on synthesizer design:
Who needs waveform generation (for calibration and/or for measurement).
Frequency bandwidth: Fmin / Fmax.
Frequency steps (∆F) and duration.
Sinwave or other shapes (triangle, ramps…) ?
Sweep or emission occurrence.
Analog interfaces (number, level, impedance…).
Synchronous emission/acquisition (absolute phase information).
Will you need specific control of synthesizer ? (control frequency step, amplitude modulation…).
Level of design integration.

4. Resources for BEPI (synthesizer only)
Mass:
AM²P-E mass : 250 g (A5 size board without frame)
Power:
Need to have more inputs
BEPI: <1W max.
