Advanced Diagnostics

Warning! Only qualified service personnel should access the internal components of
the IS1001 reader or perform the advanced diagnostics described in this section.
The advanced diagnostics described in this section can be performed with the help of an
oscilloscope.

Monitoring Antenna Current

Attach a current probe (Tektronix P6021 or equivalent) to either one of the antenna leads.
This is used to:
•
Verify that the IS1001 reader's antenna is tuned properly
•
Check that current measurement is well calibrated.

Monitoring FDX-B Tag Signal Decoding Filters Output

Connect a voltage probe to the white "BFLTR" test point TP16 on the Mother Board. If HDX
detection is enabled, attach another voltage probe to the white "HDX_EN" test point TP7 on the
Mother Board and trigger the view of the oscilloscope by the falling slope of this signal. The
probe's ground leads can be attached to the shield SH1 on the Mother Board.
This is used to:
•
Check for the presence of excessive noise and help determine its source
•
Verify the integrity of an FDX-B tag signal.

Monitoring HDX Tag Signal Decoding Filters Output

Connect a voltage probe to the white "HFLTR" test point TP15 on the Mother Board (located
inside the shield SH1). Attach another voltage probe to the white "HDX_EN" test point TP7 on the
Mother Board and trigger the view of the oscilloscope by the rising slope of this signal. The probe's
ground leads can be attached to the shield SH1 on the Mother Board. HDX detection must be
enabled.
This is used to:
•
Check for the presence of excessive noise and help determine its source
•
Verify the integrity of an HDX tag signal.
