Included with the Arbitrary Waveform Generator is a full featured Function Generator and Pulse Generator. The function generator offers a set of pre -stored waveforms, which are generated using the Arbitrary Waveform system. The Pulse Generator allows the user to generate pulse waveforms with varying amplitude, offset, frequency and duty cycle.

1.2 Feature summary

∙Each unit is individually calibrated to ensure accurate output frequency, level, and offset voltage.

∙Output level: 4mVp -p to 20Vp -p (unloaded). Output level can be entered with 1 mV or .1 dBm resolution.

∙Output offset: 0 mV to +/- 6.0 V. Output offset can be entered with 1 mV resolution.

∙TTL/CMOS compatible logic output drives digital circuits directly.

∙Flash Memory is used for code storage to enable easy software updates.

∙10 complete instrument setups can be individually stored or recalled.

∙Unit has a large, easy-to-read illuminated LCD display, which shows all operating parameters for each setup. No confusing submenus.

∙Full numeric keypad and rotary encoder make entering and adjusting parameter values easy.

∙Standard RS232 port included. Remote control operation requires no special hardware or software. Baud rate is programmable. All commands use ASCII characters. Programming examples are included.

∙External modulation input is wideband: DC to 35 KHz. High input impedance (30K O avoids loading the source signal.

∙External logic input allows user to gate output signal on/off under logic control. It can also be used as an external trigger signal.

External FSK and BPSK data is also brought in on this connector.
