Installation

1. Inspect the shi

pping carton for external damage, which indicates possible

damage to the instrument.

2. Remove the RTX

130B from the shipping carton.

3. Check that the instrument has not been damaged in transit. The exterior should not have any s

cratches or impact marks. Before shipment the instrument is

thoroughly inspected for mechanical defects.

NOTE. Save the shipping carton and packaging materials for instrument

repackaging in case shipment becomes necessary.

4. Verify that the shipping carton contains the instrument, the standard accessories, and any optional accessories that you ordered.

5. Perform the functional check procedure after installing the instrument. (See page 1-9, Functional Check Procedure.)

Contact your local Tektronix Field Ofﬁce or representative if there is a problem with your instrument or if your shipment is incomplete.

Environment Operating

Requirements

Before you install the instrument, refer to the General Safety Summary section at the front of this manual for power source, grounding, and other safety information.

Verify that the location of your installation has the proper operating environment.

CAUTION. Damage to the instrument can occur if this instrument is powered on at

temperatures outside of the speciﬁed temperature range.

CAUTION. The instrument does not have a power switch, but does have an

on/standby switch. When you connect the power cable to the AC line connector, power

is applied to the power supply standby circuit of the instrument. Read the power application instructions before plugging the power cable into a power source. (See page 1-6, Applying Power to the Instrument.)

Verify that you are using the proper power cord for your location. (See page 1-6, Applying Power to the Instrument.) Connect the power cord from the rear-panel power connector to the power system.

CAUTION. The instrument is shipped with a power cord appropriate for use with

your power systems (normal 115 V power system or 230 V power system). If the

nstrument is to be used with a power system other than that speciﬁed in the order,

i the power cord must be replaced with one appropriate for the power source used. (See Table 1-1 on page 1-2.)

Applying Power to the

Instrument

After you have veriﬁed the operating environment, AC line, and power cord requirements, plug the power cord into the power connector on the rear panel, and then plug the power cord into the local power s ource. (See Figure 1-1.)

Update Method:

Specify the method to update PCR/PTS/DTS. The optional interface supports both Software or Hardware update methods but IP interface supports only the software method.

Hardware: PCR/PTS/DTS are updated using the counter values of the 27 MHz clock on the output board. Since data output and PCRs are completely locked, the continuity of PCRs is maintained at the loop point even if playing long stream loops. However, timing errors occur in PTS/DTS.

Software: PCR/PTS/DTS are updated by adding the actual looping time (deﬁned by the start and stop positions) to the stream every time it is looped. However if there are no timing errors in PTS/DTS, it is difﬁcult to maintain the continuity of PCRs at the loop point because the updating is not synchronized with the 27 MHz clock on the output board. Since this method is used to update NPT, if you enable the NPT option, Software is selected automatically.

ASI Format Sets the output format of the ASI signal. You can select Byte or

RF Output Sets whether to output an RF signal from the RF Output connector.

You can select On or Off. When you select On, the outputs from the ASI/SMPTE Output and SPI In/Out connectors stop. Also, the clock rate is ﬁxed to the rate that is calculated from the symbol rate and RF parameters.
