
Length (bytes): 1

Default value: 100%

The values for the modulation depths are in steps of 10, ranging from 10% to 100%.

The values are the hex equivalent of the corresponding modulation depth.
Table 13-4: Common Modulation Depth Values
Modulation Depth (%)
Hex Equivalent
30 0x1E
80 0x50
90 0x5A
100 0x64

The modulation depth is calculated by the reader using the equation:
(V
MAX
– V
MIN
)/V
MAX
where V
MAX
is the RF voltage when transmit power is maximum and V
MIN
is the RF
voltage when the transmit power is minimum. (For 100% modulation depth, V
MIN
equals zero.)

See the manufacturer’s tag data sheet for the modulation depth supported for the tags in your
application.
