Does anyone know the command to perform just a RESPONSE-THRU command with the 8753D. I can activate the RESPONSE menu to pop up OPEN, SHORT and THRU, but I can't seem to find the 8753D's command to execute the THRU. I can also execute the RESPONSEDONE command, but the analyzer errors out with ... more standards required because the OPEN, SHORT, or THRU commands have not been sent. I have tried just about every command that I could find that deals with the calibration of the unit.bfkmkabp bfkmkabp bfkmkabp bfkmkabp Thanksbfkmkabp bfkmkabp |

| 1 | lassa | The command you need is probably STANC; Look at page 391 (7.25) in this document: http://cp.literature.agilent.com/litweb/pdf/08753-90475.pdf for an example of the response cal. In the case of response cal, there are no classes, so you don't send the class command, but just the "measure standard X" comand where the choices (for your cal kit) are A, B, C (first second third). In this case, the thru is the third standard, hence STANC. Note, you only send 1 of these (some folks think for a response cal, you first put on an open and do OPEN, then apply a short and do "SHORT" then apply a thru an do "THRU", but this is not correct. Really, the standard tells the channel what to assume the response should be. If you choose a "thru", the response will have the loss of the thru standard (typically 0 dB, 0 phase, but it is possible to define a non-zero length thru). The open response is about 0 dB, with a phase corresponding to the delay and open ckt capacitance; a short is 0 dB with a phase of 180 degrees, plus any delay in the standard definition. .... I know, too much information. |
