User Manual 9260
Portrayal 1-5
Channel 2 Input
This input connector accepts signals within the range of DC to over
35 MHz and amplifies them by a fixed gain. The gain is normally
x10 however, this number may be different if you ordered the
amplifier with different gain setting. Input impedance is factory pre-
conditioned and has one of the following values: 50
, or 1M
.
1M
input impedance can be used for low frequency signals (up to
100kHz) however, higher frequencies require 50
termination at
the input of the amplifier to eliminate standing waves and
reflections in the input cable, which can cause excessive ringing
and aberrations at the output.
The amplifier input cannot tolerate high voltage on its 50
resistance. Therefore, before applying the cable to the input
connector, make sure your signal will not exceed input rating, as
specified in Appendix A of this manual.
Note
Channel 2 Input is disabled when the 9260 is
configured to operate in differential output mode.
Channel 1 Output
The channel 1 output connector outputs amplified signals. When
the 9260 is configured as two separate amplifiers, this output
connector generates amplified signals that are applied to the
channel 1 input connector. If the instrument is configured for
differential output, this channel generates normal, non-inverted
signals while the other output connector generates the inverted
signal at 180
phase offset.
Gain at this output is fixed at 10 (or another gain factor that was
specified at the time of your purchase). Output source impedance
is 0
.
WARNING
Applying the output signal on inductive or
capacitive loads may damage the amplifier.
Channel 2 Output
The channel 2 output connector outputs amplified signals. When
the 9260 is configured as two separate amplifiers, this output
generates amplified signals that are applied to the channel 2 input
connector. If the instrument is configured for differential output, this
channel generates an inverted signal at 180
phase offset while
channel 1 output generates the normal, non-inverted.
Gain at this output is fixed at 10 (or another gain factor that was
specified at the time of your purchase). Output source impedance
is 0
