BERKELEY NUCLEONICS CORPORATION 645 50 MHz Function/Arbitrary Waveform Generator

The BNC 645 50MHz Function/Arbitrary Waveform Generator delivers many advanced features and user modes. New DDS+ technology embraces advancements in the semiconductor industry and leverages state-of- the-art components for both standard and complex functions.
The Model 645 can generate variable-edge pulses at rates up to 10MHz. From the front panel or through remote communications, the user may vary the period, pulse width and amplitude. The pulse parameters may be stored in the unit or on your computer for later recall.
The BNC 645 offers 14-bit resolution and a 125 MSa/s sampling rate, giving users enough control of their waveforms for most applications. It will storage of up to 5 waveforms concurrently ( 4 waveforms (4 x 256K points) in nonvolatile memory and 1 waveform in volatile memory.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
