Available output signals from the model 4830A include single-ended and differential charge (pC), single-ended voltage (mV) and current-sinking Isotron (IEPE). The further inclusion of a tachometer (TTL) output signal makes the unit a convenient and portable means of on-site instrumentation testing and servicing. Simulated outputs are available in either English or Metric units over an available frequency range of 1Hz to 10 KHz, with an adjustable output amplitude of up to 10,000 pC or mV pk and with overall noise of <2 mV or 2 pC rms.
In addition, the model 4830A uses a menu-driven 80-character LCD display to establish appropriate settings. The key panel contains four sealed switches (per IP65) marked with arrows for cursor control. In addition to the manual on/off switch, the unit can be set for automatic power shutdown. The last setup is automatically stored within its non-volatile memory. Units are powered by internally mounted batteries, which are fully rechargeable from a regulated 9 VDC power source. The power supply and a carrying case are included.
