6.15 Programming Example
# use the PyVISA plugin from http://pyvisa.sourceforge.net/
import visa
import time
def pause():
print 'press return to continue'
cont=raw_input()
# instrument setup, change addresses to suit your equipment
address = "ASRL46" # e.g. "GPIB::18" for GPIB address 18, "ASRL15" for COM15
#
(FTDI driver enables COM over USB)
timeout = 1000
resetN4960A = True # option to reset the instrument when starting
# connect to instrument and turn off local echo if using USB
# -local echo may be on or off, which means the !ECHO OFF
# command may be repeated back to us, this is tricky
print "connecting to " + address
N4960A = visa.instrument(address)
N4960A.clear
if (address.find("ASRL") != -1):
N4960A.write("!ECHO OFF")
N4960A.timeout = 1
try:
tmp = N4960A.read()
except:
N4960A.clear
N4960A.timeout = timeout
# clear errors
