Waveform Synthesizer Interface
Connector Type: The analog I/O connector is a female 37 pin subminiature D type.
Bandwidth: 0 to 22 kHz depending on the user selected sample rate.
Noise Level: At least 50 dB below nominal signal level of 0 dBm at 1 kHz
Crosstalk: At least 50 dB below nominal signal level of 0 dBm at 1 kHz
Output Drive: Compatible with an amplifier’s balanced input impedance of 600 ohms or greater,
and a maximum output capability of 6Vp-p.
Input: Compatible with an amplifier’s balanced output impedance of 600 ohms or less, and capa-
ble of receiving a maximum 3Vp-p signal.
Connector Pinouts: Connector pin out for the Waveform Synthesizer is shown in Figure 9.
