scp_selftest
This command does an internal self-test of the scope card.
Usage
int scp_selftest(int instr_id)
instr_id
The instrument identification code of the scope card
Details
The scope card must be initialized before using this command.
This command returns a 0 if executed without error; a negative number indicates an error.
Example
Status1 = scp_selftest(SCP2);
Does a self-test of scope card 2 (SCP2).
Also see
scp_init (on page 3-67)
scp_setup
This command sets the start, stop, and step (scan resolution) frequencies of a scan.
Usage
int scp_setup(int instr_id, double min_freq, double max_freq, double res_bandwidth)
instr_id
The instrument identification code
min_freq
Start frequency of the scan in Hertz (Hz)
max_freq
Stop frequency of the scan in Hz
res_bandwidth
Step size (scan resolution in Hz):
