AC Input

This rear-panel ac power module or jack senses the incoming voltage and automatically selects the proper setup. The nominal ac input range is 100-132, 175-240 Vac, 47-63 Hz, 40 VA.

INPUTS A and B Ports

These rear-panel 50Ω BNC input connectors or ports allow two-input signal connection to the 58502A. These ports will accept sinusoidal signals, ranging from 100 kHz to 10 MHz with power level of +7 to +15 dBm.

These ports form a 2-to-1 auto-switch. When the 58502A detects that one of its inputs is removed or the amplitude of the input is greatly reduced, it will automatically switch to the other input. Thus, the auto-switch feature ensure your critical frequencies are always present.

Only one input is used at a time. Factory default is set to input A over B if valid signals are present at both ports.

If input A signal goes away while there is a signal at input B, the auto-switching feature automatically switches to using the input B signal. However, if the input A signal returns, the 58502A will continue to use the input B signal. It will not return to using the input A signal until you send the SCPI commands INP:SEL A and INP:SEL:AUTO 1.

11 12 OUTPUTS (1-12) Ports

These twelve 50Ω BNC, rear-panel connectors or ports allow distribution of sinusoidal signals (ranging from 100 kHz to 10 MHz) with very low phase noise and signal distortion. The isolated output signals are derived from a single sine wave input signal, from input A or B. The outputs have fixed and identical characteristics, and retain the integrity (that is, frequency, amplitude, phase, etc.) of the input signal. The state of each distributed output signal is communicated via the front-panel indicators or LEDs, and can be monitored at the ALARM/STATUS port.
