This powerful and flexible combination accurately sweeps the characteristic curves of diodes, triode, tetrodes, and pentodes in real-time. A special A/B comparison mode allows perfect tube matching by overlapping both sets of curves. A digital readout displays plate and grid bias voltages, cathode current, transconductance gain, and output conductance (1/rp) .  \nSpecifications  \n\n| Item | Specification |\n| --- | --- |\n| Plate Voltage | 0V to 380V @200mA |\n| Cathode Current | 0mA to 100mA (200mA in 2A mode) |\n| Grid Step Sizes | 0.5V, 1V, 2V, 5V, 10V (8 steps) @5mA |\n| Plate Power | 20W peak |\n| Screen Voltage | 100V to 300V @25mA |\n| Transconductance | 0. 1mA/V to 20.0mA/V |\n| Output Conductance | 0.001mA/V to 2.000mA/V (1000k to 500 ohm) |\n| Basic Accuracy | 2% voltage and current, 5% conductance |\n| Output Signal Gains | Plate/Screen: 10mA/V\u003Cbr>Grid: -50mV/V\u003Cbr>Cathode: 40mV/mA |\n| Intensity Modulation | 5V TTL levels, low on, high off |\n| Heater Supplies | 6.3V @5 amp\u003Cbr>5.0V @3 amp |\n| Socket Adapter Cards | Dual Triodes: 8 and 9 pin\u003Cbr>Pentodes: 8 pin (A and B)\u003Cbr>Power: 5V Diodes and 2A3/300B\u003Cbr>Blank: (wire up you own socket) |\n| Input Voltage | 120Vac or 240Vac, 50W |\n| Fuse | 1 amp 5x20 slo-blo |\n\nSocket Adapter Cards  \nSocket adapter cards are employed to accommodate various tube pinouts. These cards plug onto the connector at the top of VacuTrace and are held in place by four wing nuts. They are built to be rugged and quickly swapped with one another. A socket adapter card must be installed before a vacuum tube can be tested. Standard cards included with VacuTrace are:  \n• Dual 8 and 9 pin triodes (12AX7A/6DJ8, 6SN7)  \n• Octal pentode power tubes (6L6GC, KT88)  \n• Power triodes and diodes (2A3/300B, 5Y3)  \n• Jumper (any 7, 8, or 9 pin tube)  \nConnections  \nConnecting a VacuTrace is simple. Use the BNC cables provided to connect the X, Y and Z outputs to your oscilloscope.
