This item was fully tested using frequency counter and oscilloscope. The signals generated by this equipment remain clean and without distortion despite of its old age. Never been repaired and Internally clean as good as original condition. All control buttons and adjustment knobs works very satisfactory and without damage. The BNC terminals are in good condition though with sign of old age. The face-plate shows noticeable discoloration with some minor scratches on its case. Works on 110, 120, 220 and 240 VAC internally switchable.
