• 1, 5, 10 MHz external reference capability—to match customer’s house
standard (however, the HP 53132A’s external reference capability is
10 MHz only),
• optional ultra-high stability , high stability, or medium stability oven
oscillators for high accuracy needs,
• external gating,
• statistics,
• automatic limit testing,
• SCPI programming capability, and
• analog display mode limit testing
Programmable control is performed via an HP-IB. The HP-IB and a
talk-only RS-232C serial port are standard for the HP 53131A/132A/181A.
The serial port is for printing measured and analyzed data on serial
printers, or for outputting an out-of-limit signal.
