NR/SR-33000 / SR-33500/ TRX-SR V-Phasing
A V-phasing feature, available with the NR-33000, SR-33000 with Rev B
FPGA Software Update, and SR-33500 allows the user to adjust the switch
point from the -1 line to +2.5 lines relative to the nominal switch point for
the video standard being used. This is accomplished with the following
DIP switches:
• NR-33000 DIP switch S3 (shown on Figure 88 on page 174 )
• SR-33000 DIP switch S2 (shown on Figure 89 on page 175 )
• SR-33500 DIP switches S102/S103 (shown on Figure 90 on page 176 )
• TRX-SR DIP switches S1-S4 (shown on Figure 91 on page 177 ).
Table 26 shows the switches providing adjustment relative to Reference A
(“Reference 1” on SR-33500). For SR-33000, “On” = switch closed.

Table 27 shows the switches providing adjustment relative to Reference B
(“Reference 2” on SR-33500). For SR-33000, “On” = switch closed.
