Toggles the sampler correction routine ON,
for normal operation, or OFF, for diagnosis or
adjustment purposes
Normal operating condition and works in
conjunction with IF GAIN ON and OFF. The
assembly includes a switchable attenuator section
and an amplifier that
low-level 4
IF signals (for A and B inputs only). This mode
allows the
IF section to automatically determine
if the attenuator should be switched in or out.
The switch occurs when the A or B input signal is
approximately -30
Locks out the
IF attenuator sections for
checking the
IF gain amplifier circuits,
regardless of the amplitude of the A or B IF signal.
Switches out
both
the A and B attenuation circuits;
they cannot be switched independently. Be aware
that input signal levels above -30
at the
sampler input will saturate the ADC and cause
measurement errors.
Switches in both of the
IF attenuators for
checking the
IF gain amplifier circuits Small
input signals will appear noisy, and raise the
apparent noise floor of the instrument.
For factory use only.

Allows you to store the correction constants that
reside in non-volatile memory
onto a
disk. Correction constants improve instrument
performance by compensating for specific operating
variations due to hardware limitations (refer to the
“Adjustments” chapter). Having this information on
disk is useful as a backup, in case the constants are
lost (due to a CPU board failure). Without a disk
backup the correction constants can be regenerated
