SPG8000 Specifications and Performance Verification
TEMPERATURE: Verify that the following board temperature readings
are normal (OK) by pressing the right (►) arrow button to view each
reading. Record Pass or Fail in the test record.
NOTE.
Option GPS only: For GPS modules with a GPS/GLONASS receiver
that are installed in an instrument with firmware version 1.5 or above
installed, the REF temperature readout is N/A because there is no temperature
sensor on the receiver.
Main
CPU
REF (Option GPS only)
SDI (Option SDI only)
FPGA (Option SDI only)
VOLTAGE: Verify all voltages are normal (OK) by pressing the right (►)
arrow button to view each of the following voltages. Record Pass in the
test record if all voltages are normal or list any failed voltages.
NOTE. If you do not see a specific voltage on your instrument, it is because
your instrument does not have the related hardware option installed.
Slot 1: +5.0 V Slots 1 & 2: +8.0 AV
Slot 2: +5.0 V Slots 3 & 4: +8.0 AV

arrow button to view each of the following fan speeds. Record Pass or
Fail in the test record:
Main
PS1
PS2 (Option PDW only)
Power Supply 1: Verify temperature weighted hours (Tmp Wtd) and
voltage (V) is normal (OK). Record Pass or Fail in the test record.
