NOTES

1. It is recommended that the magnetron should be isolated from the load by means of an isolator
of approved design.
Information on the characteristics of a suitable isolator may be obtained from e2v technologies.

2. With no anode input power. It is recommended that a DC power supply is used to operate the
heater. Use of an AC supply may result in damage to the heater circuit.
The use of an AC heater supply during HT operation may result in frequency modulation of the RF
pulses. Contact e2v technologies for further information.
The heater voltage must be reduced within 5 seconds after the application of HT according to the
schedule shown on page 4.
The magnetron heater must be protected against arcing by the use of a minimum capacitance of
4000 pF shunted across the heater directly at the input terminals; in some cases a capacitance
as high as 2 mF may be necessary depending on the equipment design.

3. The tuner mechanism is driven by means of three tapped holes in the tuner knob(see outline drawing)
via a flexible drive. The torque required is 0.7 kg-cm minimum; the torque applied must not exceed
5.0 kg-cm.

4. To minimise frequency deviation when the magnetron is rotated about a horizontal axis, this axis
should be parallel to the axis of the tuner.
