4.
Optional. You can enable alarm sound that goes off if the measurement falls outside of the limit.
Toggle the Beep soft key between On and Off to enable or disable the beep sound.
5.
Optional. Go to SAVE/LOAD > Save, and then select Limit to save the limit settings.
See "Using save" on page 31 for more information.
NOTE
The Time Offset compares the PN offset timing with the overall system time and the
instrument checks the start of PN offset in comparison to either the GPS signal or the
even second clock signal.
NOTE
The Carrier Feed Through is a result of the RF carrier signal feeding through the I/Q
modulator and riding on the output circuitry without being modulated.

Performing auto measurements

The Auto Measure function of the JD780A series allows a complete signal profiling covering RF
characterization and modulation quality parameters of up to 10 different carriers, particularly useful on
an overlay architecture where base stations are transmitting in different frequencies.
The Auto Measure can be easily executed either by selecting a menu in the instrument or by running a
programmed scenario in the PC-based application so that the instrument automatically configure and
perform tests on every aspect of all the carriers.

Setting limit for auto measure

You can set test limits for test item(s) in the auto measurement.
Procedure
1.
Press the LIMIT hot key.
2.
Press the RF Test Limits soft key, and then enable test limits as desired.
3.
Press the PvsT Test Limits soft key, and then enable test limits as desired.

5.
Optional. You can enable alarm sound that goes off if the measurement falls outside of the limit.
Toggle the Beep soft key between On and Off to enable or disable the beep sound.
6.
Optional. Go to SAVE/LOAD > Save, and then select Limit to save the limit settings.
See "Using save" on page 31 for more information.

Setting measure setup

After configuring test parameters as described in the "Configuring test parameters" on page 373, you
can continue your measurement. The measurement settings can be saved and recalled as a file. You
can also use JDViewer, PC application software to configure a measure setup, save as a file, and load
the file on to the instrument.
Procedure
1.
Press the MEASURE SETUP hot key.
2.
Toggle the Configuration soft key and select the configuration option:
