and amplifies an external input signal applied to the HI and
LO IN terminals. For fixed gain amplifier operation, the
6826A has a frequency response from DC to 40kHz and the
6827A has a frequency response from DC to 30kHz. The
fixed voltage gain provided in the high or low output range
is as follows:
3-8 In variable gain amplifier operation, the BPS/A can
amplify or attenuate an external input signal (dc to 15kHz)
applied to the Hi and LO IN terminals. The gain is variable
from 0 to a maximum depending upon the RANGE switch
( 4 ) and VOLTAGE control ( 5 ) settings. The variable
gain ranges are as follows:
3-10 RANGE SWITCH
3-11 The RANGE switch (4) allows selection of the
high (X10) or tow (XI) output ranges for power supply,
variable gain amplifier, or fixed gain amplifier operation.
The REMOTE position allows the high or low range to be
externally selected via the rear terminal strip (see Paragraph
3-9 In fixed gain amplifier operation, the BPS/A inverts 3-45).
