Timebase Adjustment
C A U T I O N
Before performing this procedure, you must have firmware revision A.02.00 or higher installed
in the Agilent 86100A/B. Refer to the Agilent website (www.agilent.com/comms/DCA) for
instructions on obtaining the latest firmware revision). Trying to adjust the mainframe timebase
with older firmware will cause timebase accuracy failure. After the DCA mainframe’s timebase
is adjusted, you can not install a version of firmware below A.02.00. Timebase failure will occur.
Procedure
1 Make sure the instrument cover is in place.
2 Install the plug-in module into the mainframe left-hand module slot, then tighten both screws.
3 Turn on the mainframe. After the boot-up is complete, press the Default Setup hardkey on the
DCA front panel.
4 Turn on the electrical channel by pressing the CHANNEL 2 hardkey on the DCA front panel.
Turn all other channels off.
5 On the DCA front panel, set the trigger source to Free Run by pressing the Source hardkey until
Free Run is selected.
N O T E
Allow all of the equipment to warm up for at least one hour in the settings specified above before
you proceed. These settings are optimal for generating typical operating conditions.
6 Set the timing generator controls as follows:
a Turn on the timebase EXT and EXT DIVIDE, and set to divide by one
b Set the CHANNEL 2 output as follows:
SQUAR ON
AMPL 2.4 V
OFFS 0 (If needed, adjust the offset to center the output around 0 V.)
DISABLE OFF
c Set all other controls to zero or off.
7 On the synthesized CW generator, press PRESET, then set the controls as follows:
FREQ 500 MHz
POWER LEVEL -14 dBm
RF ON/OFF to OFF
N O T E
If the Synthesized CW Generator does not have Option 1E1 installed, insert a 10 or 20 dB
attenuator at the RF OUTPUT and set the POWER LEVEL so that the power going to the
electrical channel is -14 dBm. (Example: 10 dB attenuator = -4 dBm; 20 dB attenuator = +6 dBm.)
8 Ensure that everything is disconnected from the electrical plug-in input.
9 On the DCA screen, press Calibrate..., All Calibrations..., Module, Calibrate Left Module, then
press Continue.
10 After the successful completion of the calibration routine proceed to the next step.
