About the Data Output Source
When you output the selected stream data, you can select either the hard disk or the
RAM as the output source. This subsection describes the operation of the
RTX130A when each output source is selected.
Operating Basics
RAM
Hard Disk
When you select the RAM as the output source, the RTX130A performs the
following:
When the data output rate is less than or equal to 120 Mbps, the RTX130A
outputs the first stream data while transferring the data from the hard disk to
the RAM and then continuously outputs the data from the RAM using looping
methods.
When the data output rate is more than 120 Mbps, the RTX130A continuously
outputs a stream data from the RAM using looping methods after the data is
completely transferred from the hard disk to the RAM.
If you select the RAM as the output source, you cannot output the data over the
RAM free space for the data output (maximum 256 MB). This RAM free space is
displayed on the status bar. Refer to Status Bar on page 2-10 for more information
about the status bar.
If you select the hard disk (Disk) as the output source, the RTX130A always
outputs the selected stream data from the hard disk regardless of the data output
rate. When the reading speed of the hard disk cannot overtake the data output rate,
the error message “Error: Output Buffer Empty” appears.
Use the Source command in the Play menu to select the output source. Refer to
Play Menu on page 3-5 for more information about the Play menu.
You can see the currently selected output source in the status bar. Refer to Status
Bar on page 2-10 for more information about the status bar.

Command Description
Packet Size Sets the packet size (in bytes) for the stream. You can set the packet size
to 188 (188 + 0), 204 (188 + 16), 208 (188 + 20) bytes, or Non TS.
These packet sizes can only be set for an MPEG2 transport stream. For
an S-TMCC or M-TMCC transport stream, the packet size is fixed to 204.
For a Non TS stream, the packet size is fixed to Non TS. The packet size
is fixed to 188 when you set RF Output to On in the QAM/VSB menu.
When you select Non TS, the RTX130A deals with stream data in a byte
unit (not a packet unit) and outputs all of the data in a file. If a transport
stream contains any error, you can output it by selecting Non TS.
Clock Opens Clock dialog box where you can set the clock rate of the stream
output.
Refer to Clock Dialog Box on page 3-7 for more information.
Update Sets whether to update parameters in the stream when looped. You can
select On or Off. You cannot select to On for a Non TS stream.

the clock rate using the following methods (the first method provides greater
clock-rate precision):
Enter values into the numerator and denominator text boxes (see Figure 3-2 on
page 3-7). The RTX130A will then calculate the clock rate based on the ratio
of the numerator and denominator values.
Enter a value into the clock rate text box. The RTX130A will then calculate the

Since the default clock rate is calculated based on the PCRs in the downloaded
stream file, the value can be different than the original clock rate. When the
elementary stream rate is fixed (refer to the Fixed ES Rate description), the
instrument refers to the default clock rate. Therefore, if the default clock rate
is different than the original clock rate, you need to set the value to the
appropriate value. If you change the value, the clock rate value in the Data Rate

Async: Uses the internal clock, which is not synchronized with the clock that
is created by an ASI or SMPTE310M signal, for real-time modulation.
In this mode, the input transport stream clock is not synchronized with the
symbol rate. The transport stream rate that is calculated by the symbol rate and
modulation parameters are synchronized with the actual transport stream
signal by inserting null packets. In this case, PCR jitter of maximum 1 packet
generates.
NOTE. If the bit rate of the input transport stream is higher than the calculated bit
rate, a non-modulated signal is output.
Ext Ref: Uses a signal applied to the Clock/Ref In connector as the reference
