Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Writing Gun | 10000 V | — | — | — | — |
| Reading Gun | 1500 V | — | — | — | 0.0005 mA |
Application Notes
The input signal is applied to the writing gun electrode; the spot must never remain stationary to avoid target damage. The output signal current is approximately 0.5 microamps.
