Is it possible to generate the "pulse" function with external trigger, or external triggering is possible only with "sweeps" function?
If it isn't possible, how can I generate a trapezoid wave that will be triggered externally?
Using simple remote programming is not an option, because I need to trigger 2 devices at once with maximum time difference of ~10us, which is the situation with hardware external triggering, while when using remote programming (e.g. with matlab) the time difference is ~100us.

Or do you also have the 2182A nanovolt meter?
If you have only the current source and you want it to generate a pulse of current when an external digital trigger occurs, you could make use of the custom list sweep to compose the pulse shape.
Below are the SCPI commands for a simple three point list to generate a 20mA amplitude pulse for 100msec with 3 volt compliance value.
The instrument will wait for the digital trigger (at line 1 on trigger link) to arm. When received, it will move into trigger layer and carry out the list sweep. See figure 8-2 in 622x Reference Manual.
