2. Touch the bit rate specifications button.
The number displayed in the button is the specified bit rate (bit/s).
When indicating 1.25G, this means 1.25 Gbit/s.
3. When selecting [Variable], touch the bit rate and offset text boxes
and input the value. The bit rate can be set in the range 125 MHz to
12.5 GHz, and the offset can be set in the range –100 to 100 ppm.
If the Option 092 is not included, select [Variable], [Variable-1/2],
[Variable-1/4], [Variable-1/8], [Variable-1/16], [Variable-1/32],
[Variable-1/64], and input values in the ranges shown in Table 5.5-1.
Table 5.5-1 Bit Rate Setting Ranges Without Option 092
Specifications Bit Rate (kbit/s)
Variable 8 500 000 to 11 320 000
Variable-1/2 4 250 000 to 5 6600 000
Variable-1/4 2 125 000 to 2 830 000
Variable-1/8 1 062 500 to 1 415 000
Variable-1/16 531 250 to 707 500
Variable-1/32 265 625 to 353 750
Variable-1/64 132.813 to 176 875
To set amplitude
1. Touch the Amplitude text box and set the amplitude voltage.
2. Insert an attenuator between the
Data
Out connector and the Data
Out connector, and touch the External Attenuation text box and
input the attenuation. The amplitude voltage after passage through
the attenuator is displayed in Relative.
CAUTION
When inserting attenuator at both the Data Out connector
and Data Out connector, use an attenuator with the same
amount of attenuation.
If the attenuation amounts are different, the displayed
amplitude and the amplitude output at the connector will
be different.
