MIL-M-38510-121 Microcircuits, Linear Monolithic And Multichip, Silicon 12 Bit Digital-To-Analog ConvertersThis specification covers the detail requirements for monolithic silicon, bipolar, interface, memory core drivers. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3

5. (Cont):

Increase the vertical plug-in gain to 1 mV/cm and the horizontal gain to 1 μs/cm. Toggle 81 to ground and observe the shift in the amplifier output. This is the value of 1 L8B and should be approximately 2.4 mV. With 81 in position

2, observe the amplifier output level at 10 μs. It should be completely settled and unchanged from the 1 μs value. Any significant magnitude variations must be resolved before proceeding to measure OUT settling time. (If a significant change between 1 and 10 μs is noticed, it is probably due to a thermal unbalance in the amplifier fixture rather than a problem with the OUT. To check this, perform a t8HL measurement between 1 and 10 μs. If the change is similar but of opposite polarity, it can be attributed to the fixture and ignored.)
