Clock
The general- purpose clock output is derived from the internal time base.
The output clock is divided down from the time base clock such that:
The time base frequency is 40 MHz. The divisor can be an integer from
2 to 4
The valid values for the clock output rate are: 20 MHz, 13.33 MHz,
10 MHz, 8 MHz, 6.667 MHz, ... 10Hz. The clock output frequency will round
to the nearest achievable frequency.
The commands used to control the clock output are:
SOUR:MOD:CLOC:FREQ {<freq>|MIN|MAX|DEF},<slot>
SOUR:MOD:CLOC {OFF|ON|0|1},<slot>
You can obtain the rounded value of the currently set clock frequency
using the following query.
SOUR:MOD:CLOC:FREQ?
You can also set the logic "1" voltage level for external clock output.
For example, the following command sets the output clock level to 4.5 V
for the module in slot 5.
SOUR:MOD:CLOC:LEV 4.5, 5
24
Clock Output (Hz) = (time base frequency)/(divisor)
6
providing a range of 20 MHz to 10 Hz for the clock output.
