Timebase Commands
BRATe
Timebase Commands
The TIMebase subsystem commands control the horizontal (X axis) analyzer functions.
BRATe
Command :TIMebase:BRATe <bit_rate>
This command sets the bit rate used when the time base units are bit period. <bit_rate> is
the bit rate (in bits-per-second).
Query :TIMebase:BRATe?
The query returns the bit rate setting.
Returned Format [:TIMebase:BRATe] <bit_rate><NL>
Examples The following example sets the bit rate to 155.520 MHz.
10 OUTPUT 707;":TIMEBASE:BRATe 155.520E6"
MPOSition
Command :TIMebase:MPOSition <trigger_delay>
Reduces the trigger's Minimum Timebase Position. Use in Jitter Mode when making measure-
ments on devices that employ a modulated clock. Jitter measurements on devices with a
modulated clock can result in artificially higher measured jitter levels, due to the 86100C's
trigger delay. Reducing the Minimum Timebase Position reduces the amount of observed jit-
ter. The default value is 40.1 ns. Reduce to its minimum value of 24.1 ns. To learn more about
the trigger position and modulated clocks, refer Agilent Product Note 86100-5, "Triggering
Wide-Bandwidth Sampling Oscilloscopes For Accurate Displays of High-Speed Digital Com-
munications Waveforms." You can download this product note from the 86100C product page
on Agilent's web site.
Restrictions Software revision A.06.00 and above.
Query :TIMebase:MPOSition? <trigger_delay>
The query returns the current delay value in seconds.
Returned Format [:TIMebase:MPOSition] <trigger_delay><NL>
Examples 10 OUTPUT 707;":TIMEBASE:MPOSITION 20E-9"
POSition
Command :TIMebase:POSition <position_value>
