modulated (PWM, and continuous pulses that are frequency
modulated (FM).
Static State (CONDition) Function
To configure digital channels to output static states, use the
SOURce:FUNCtion:CONDition (@<ch_list>) command. Examples:
To set the upper 8 bit channel of an HP E1533 in SCP position 7 to output
SOUR:FUNC:COND (@157)
To set the lower 4 channels (bits) of an HP E1534 in SCP pos 6 to output states
SOUR:FUNC:COND (@156:159)
Variable Width Pulse Per Trigger
This function sets up one or more HP E1534 channels to output a single
pulse per trigger (per algorithm execution). The width of the pulse from
these channels is controlled by Algorithm Language statements. Use the
command SOURce:FUNCtion[:SHAPe]:PULSe (@<ch_list>). Example
command sequence:
To set HP E1534 channel 2 at SCP position 6 to output a pulse per trigger
SOUR:FUNC:PULSE (@149)
Example algorithm statement to control pulse width to 1 msec
O149 = 0.001
Variable Width Pulses at Fixed Frequency (PWM)
This function sets up one or more HP E1534 channels to output a train of
pulses. A companion command sets the period for the complete pulse
(rising edge to rising edge). This of course fixes the frequency of the pulse
train. The width of the pulses from these channels is controlled by
Algorithm Language statements.
Use the command SOURce:FUNCtion[:SHAPe]:PULSe (@<ch_list>).
Example command sequence:
