3.5.9 Output impedance. Output impedance shall be 205, ±10 ohms.
3.5.10 Recovery time. Recovery time from a 50-millisecond, 1 volt pulse input, followed
by a signal of 10-millisecond width and 50-millivolt (mV) amplitude, shall not be greater than
200 milliseconds.
3.5.11 Polarity. A polarity function shall be provided which allows the output to be in
phase or 180 degrees out of phase with the input signal.
3.5.12 AC gain balance. A potentiometer shall be provided in each postamplifier channel
which allows a 15 dB minimum ac gain balance range to balance variations in detector
responsiveness and amplifier gain variations.
3.5.13 Voltage gain drift. The average voltage gain of the 20 channels on each
postamplifier shall not differ by more than ±10 percent from the average reference gain at
ambient temperature (T = +23°C, ±5°C) over the operating temperature range of 0°C to +55°C
and by not more than ±15 percent over the temperature range of +55°C to +71°C. The average
20-channel gain shall not differ from the average reference gain at ambient by more than ±15
percent over the operating temperature range of 0°C to -54°C.
3.5.14 Output noise. The output noise of each channel shall not be greater than 150 mV
rms with the postamplifier gain set at 18,000.
3.5.15 Total signal bandwidth. The upper 3 dB frequency shall be between 72 kHz and
172 kHz. The lower 3 dB frequency shall be 6, ±2Hz. The postamplifier gain shall be flat (±0.5
dB of midband gain) from 30 Hz to 25 kHz. Midband gain reference: 0 dB at 1 kHz in both the
high and low power modes (see 3.5.5).
3.6 Environmental conditions.
3.6.1 Temperature shock. The postamplifier shall not be damaged (see 6.3.1) by sudden
changes in temperature between -54°C and +95°C.
