In the NRZ Settings Menu:
a Press the Polarity softkey and select the NRZ signal's logic type:
• High — specifies that a positive voltage is used to encode a bit value of
logic 1 (and a negative voltage encodes a bit value of logic 0).
• Low — specifies that a negative voltage is used to encode a bit value of
logic 1 (and a positive voltage encodes a bit value of logic 0).
b Press the Bit Order softkey and select the bit order, either most significant bit
first (MSB) or least significant bit first (LSB).
The selected order is used when displaying data in the serial decode
waveform and in the Lister.
c Press the Idle State softkey and choose the idle state of the NRZ bus, either
Low or High.
d Press the Idle Bits softkey and enter the minimum idle time/inter-frame gap
time of the NRZ bus in terms of the bit width.
Framing is determined by idle time.
e Use the Decode Base softkey to select between hexadecimal, unsigned
decimal, or ASCII display of the decoded data.
The decode base setting is used for the display of the data field in both the
decode line and in the Lister.
f Press the Back/Up key to return to the Serial Decode Menu.
