Output signal pull-up/input signal drive voltage
The following table shows the valid range for each of the output signal pull-up voltage and
input signal drive voltage (EXT_DCV).
The 4287A can be modified so that the input drive voltage can be used within the range
between 5 V and 9 V or 15 V and 24 V or so that the output signal pull-up voltage and
input signal drive voltage can be connected to the 4287A’s internal 5 V power supply. For
more information, contact your distributor or the Agilent Technologies sales office nearest
your site.
Table 12-6 Valid ranges for output signal pull-up/input signal drive voltage
Valid voltage range [V]
Output signal pull-up voltage 5 to 24
Input signal drive voltage 9 to 15
