MIL-PRF-49168C(CR)
3.5.7 Position reference circuitry. The Scan-Interlace shall provide circuitry for
generating a position reference waveform adjustable to an amplitude of 0.6, ±0.2 volts P-P (see
Figure 3).
3.5.8 Position error circuitry. The Scan-Interlace shall provide circuitry for generating a
position error waveform adjustable to 0.40, ±0.15 volts P-P (see Figure 4).
3.5.9 Rate reference circuitry. The Scan-Interlace shall provide circuitry that will produce
a rate reference waveform adjustable to an amplitude of 0.6, ±0.2 volts P-P
(see Figure 5).
3.5.10 Solenoid drive circuitry. The Scan-Interlace shall provide circuitry to develop and
to equalize the scanner solenoid drive waveforms, with an amplitude of 0.10, ±0.05 volts (see
Figure 6).
3.5.11 Video gate. The Scan-Interface shall provide video gate electronics capable of
generating a video gate pulse width adjustable to 2.0, ±0.2 milliseconds.
3.5.12 Side/rear phasing. The Scan-Interlace shall accept and process the tachometer and
interlace position signals in both side and rear phase relationships when properly interconnected
(see Figures 6, 7, 8, 9 and 10).
3.6 Environmental conditions.
3.6.1 Temperature shock. The Scan-Interlace shall not be damaged (see 6.4.1) by sudden
changes in temperature between -54°C and +95°C.
3.6.2 High temperature. The Scan-Interlace shall not be damaged by storage to +95°C or
continuous operation to +71°C and shall operate for 30 minutes at +95°C. The Scan Drive
waveform amplitude (Figure 2) shall not change more than ±40% from the initial setup at
ambient temperature over the specified operating temperature range (+71°C). The Solenoid
Drive waveform amplitude (Figure 6) shall not change more than ±25% from the initial setup at
ambient temperature over the specified operating temperature range (+71°C).
3.6.3 Low temperature. The Scan-Interlace shall not be damaged by operation to -54°C,
or storage to -62°C. The Scan Motor Drive waveform amplitude (Figure 2) shall not change
more than ±40% from the initial setup at ambient temperature over the specified operating
temperature range (-54°C). The Solenoid Drive waveform amplitude (Figure 6) shall not change
more than ±25% from the initial setup at ambient temperature over the specified operating
temperature range (-54°C).
3.6.4 Shock. The Scan-Interlace shall not be damaged by high intensity shock of 100 g's
peak amplitude with 11 milliseconds duration and by bench handling test.
