HARDCopy:PORT
{ CENtro nics | RS232 | GPIb | USB }
HARDCopy:PORT?
Arguments
CENtronics specifies that the hard copy data is sent out the Centronics port.
RS232 specifies that the hard copy data is sent out the RS232 port. If you set the
port to RS232, and use it to transfer a BMP screen image format file to a PC or
other computer, observe the following precaution that the BMP file is a binary
file, and therefore does not use linefeeds (hexadecimal 0a) as a terminator.
There are two ways to work around this limitation:
Write your controller program to use the byte count information in the BMP
file header.
Set your RS232 program time out value to a large enough value to guarantee
that the program does not time out before completing the data transfer. For
example, to transfer an 80 kB file at 9600 baud, set the transfer program time
out to 300 seconds.
GPIb specifies that the hard copy d ata is sent to the GPIB port. This argument is
available on instruments with a TDS2CM, TDSCMA, TDSCMAX, or TDSMM
module installed.
USB specifies that the hard copy data is sent to the USB Device port on the back of
a TDS1000B, TDS2000B, or TDS2000C Series oscilloscope only.
Examples
HARDCOPY:PORT might return RS232 as the selected hard copy output port.
HARmonics? (Query Only)
Returns settings for the HARmonic commands.

Power Measurement
Syntax
HARmonics?
Examples
HARMONICS? might return HARMONICS:ENABLE ON;SETU P AUTOMATIC;SHOW
ALL;SELECT 1;SOURCE CH1
, indicating that the oscilloscope is acquiring and
showing all harmonics and measuring the first harmonic from channel 1.
HARmonics:ENABle
Turns the harmonics measurement on or off.
