Frequency Generator

The Vernier Circuit Board 2 is a convenient platform for circuit labs, from basic series and parallel circuits to RLC circuits. Many components are provided for experimentation, and additional components can be added to expand the capability of this useful board. Specifications Size: 10 in. x 6.5 in. (25.5 cm x 16.5 cm) Mass: ~0.44 kg Optional power sources:up to 4 AA batteries, not included LabQuest Power Supply, not included (or other 5 VDC adapter with center-positive ⅛ inch connector) DC power supply such as Extech Digital DC power supply Vernier Power Amplifier Maximum voltage: 10 V Resettable fuse opens at 0.8 A, but 0.3 A or less is recommended All parts ROHS compliant What's included One circuit board Ten insulated jumper wires fitted with mini-alligator clips Five #48 lamps rated 0.06 A at 2.0 V (cylindrical body) Five #50 lamps rated 0.220 A at 7.5 V (round body) User Manual - VCB2

Use the Power Amplifier as a power supply for DC and AC circuit investigations or to drive devices such as speakers, lamps, and small DC motors. Specifications Technical Details of Power Amplifier Operation Input connection: 3.5 mm audio cable (from LabQuest or computer) or BTA cable (from LabPro CH4) Input Frequency range: DC to 15 kHz. Overall gain: 10X (LabQuest/computer), 2X (LabPro) Input impedance: 10 kΩ. (LabQuest/computer), 50 kΩ (LabPro) Maximum input ±12 V without damage. Pulse Width Modulation input used for producing DC offset or pure DC output Current Sensor Connect to Vernier interface to monitor load current There is a 0.1 Ω resistor between the black terminal and ground. Current measurements are based on the voltage drop across this resistor. Important Note: The Power Amplifier creates no signal on its own. It depends on a signal source, such as the LabQuest 2 or original LabQuest’s Power Amplifier App, our free Power Amplifier Frequency Generator software for PC/Mac, or Logger Pro 3.8 or newer (LabPro only) A LabQuest Mini or LabQuest Stream does not provide a signal source. Use the Power Amplifier Function Generator software as the signal source.
