Screening
Units are screened by lot as follows:
Thermal Shock:
10 cycles, -55 C to +100 °C, with a mini-
mum of 1/2 hour dwell time at each temperature extreme.
Attenuation is measured before and after thermal shock.
Peak Power:
500 Watts, 5
μsec
pulse width; 0.05% duty
cycle for 3 minutes at each end. DC Attenuation is mea-
sured before and after peak power.
Attenuation and SWR are tested as final electrical test. Test
data is available at additional cost.
