Description

The PRL‑175A‑10 is a battery operated, pocket-sized lab tool and troubleshooting aid. It outputs a 0 V/5V DC or 10 MHz Xtal controlled square wave signal into a Hi Z load, or 2.5V into 50 Ω. These are the essential signals for troubleshooting TTL circuits, equipment, and systems. The PRL‑175A‑10 has a 50 Ω back-terminated output driver that can drive a 100 ft long line with or without load termination. It is an indispensible tool for engineers and technicians working in the field, in the lab or on the production floor.

The included 9 V battery pack can power the PRL‑175A‑10 in square wave mode into a 50 Ω load continuously for up to 10 hours, or for 25 hours into a 600 Ω load*. An optional 4‑AA battery pack or a +9V AC adapter is also available.

The output logic mode, V_OH, V_OL or 10 MHz square wave, is selected by a 3-position toggle switch, and the status is indicated by an LED. The PRL‑175A‑10 module can be attached to the battery pack using a short strip of 3M Dual-Lock Fastener (included) and powered via a short cable terminated into a 2.1 mm DC jack. The battery pack also includes an On/Off switch, as shown in the photo above. The assembled unit fits easily into a pocket.

Applications of the PRL‑175A‑10 include precision, low-jitter clock source for testing digital systems, ADCs and amplifiers, and for simple troubleshooting applications. The PRL‑175A‑10 is housed in a 1 x 1.3 x 2.2-in. extruded aluminum enclosure and includes a 0.83H x 1.3W x 2.7L-in. battery pack.
