AC source with continuously adjustable frequency output from 10Hz to 110kHz Basic accuracies for the 1 mV to 100 V range are: 0.02% (50Hz to 20kHz); 0.5% (20 to 50Hz, 20 to 110kHz); 0.2% (10 to 20Hz). Listed elsewhere for over $500. Bought for a project that changed. Plugged in, powers up, volts & frequency go up & down. Not calibrated or otherwise tested. Fan is noisy. Shows wear & tear.
