Calibrating the 1. Some options such as rack mount handles, extra manuals etc are not that important when buying a used instrument, as but others are. The main options are: Option 1D5. This improves the frequency stability by changing the standard 10 MHz frequency reference to an oven controlled crystal oscillator OCXO.

In fact, the is such a popular VNA that we have produced a page which shows the differences between the various instruments. Before using one of our kits with an , the VNA must be setup correctly to use the kit. Entering calibration kit definitions into an series instrument. Depending on model, three or four of these methods will work. Using a floppy disk to enter the calibration kit coefficients.

This is the easiest way, but obviously only works on models that have internal floppy drives. Using the Cal Kit Manager 2. This software, available from the Keysight website, allows the coefficients to be loaded fairly easily, but there can be some compatibility issues between the software and some GPIB controllers.

From the front panel. This method works on any model in this series and does not require any other software or hardware. However, it is a bit tedious, and easy to make an error. Method 1 - Using a floppy disk to enter the calibration kit coefficients Using a floppy disk. If your VNA has an internal floppy disk drive, Kirkby Microwave can supply suitable floppy disks if we are made aware the kit is to be used with an instrument with a floppy disk drive.

If you did not request a floppy disk when ordering the kit, or have lost the disk, then let us know the model and serial number of the kit, and we can send a zipfile with the files that need to go on the floppy disk. Just unzip the files to a 1. Each calibration kit definitions will have several files with the same prefix, but different suffices. You can use a USB based floppy disk drive. You can put multiple kits on the same floppy disk. Once completed, you should ensure the disk is write protected by moving the little tab so daylight can be seen in the hole.

The delay of the thru is defined to be zero. This file includes the delay of the female-female thru, which will be around 41 ps, but is individually measured on each kit. This is quite rare, as new people use two female cables. This file includes the delay of the male-male thru, which will be around 75 ps, but is individually measured on each kit. The delay of the thru is defined to zero. This file includes the delay of the female-female thru, which will be around 80 ps, but is individually measured on each kit.

This is quite rare, as few people use two female cables. This file includes the delay of the male-male thru, which will be around ps, but is individually measured on each kit.

Once you have the floppy disk with the correct files, the method is: Power on, or press "Preset" if the VNA is already on. Insert the floppy disk Press the softkey for "Select disk" Press the softkey "Internal disk" At this point, assuming your floppy drive still works, you should get a list of the files on the floppy. Pick the one for the kit. The name should be obvious. For the N kit it will be KM For other kits, the names should be obvious. You can store multiple kits on the same disk.

Press the softkey "Return" Use the knob to select the calibration kit file. When the VNA is powered off, assuming the super capacitor supercap early models or battery later models is ok, the contents of the user defined calibration kit will be stored. There should be no need to load them again. Note however that when the instrument is rebooted, either via pressing the PRESET button or by powering it off, the calibration kit will revert to the default for that instrument.

Method 2 - Using the Cal Kit Manager 2. The procedure to use is: Obtain a. You can either Ask us to create the file, telling as the model and serial number of your kit. We will send it by email. Create the. Install the Cal kit Manager 2. Run the software, and open the. Although we have never used it outselves, being Unix fans, and not Windows fans, the Windows based GPIB toolkit has a number of useful features for test equipment.

One is a program called vna. Method 4 - Writing your own software to upload the coefficients. If you look at the programming manual for the VNA, you will see that there are various commands to set up calibration kits.

Below are a list of commands which were used to set up a custom calibration kit on one particular VNA. You need to read the programming manual. The manual for the VNA needs to be consulated carefully, but an outline of the procedure is given below, where on modifies one of the internal kits and saves it as a USER kit. That is much easier than trying to define the kit from scratch.

So an outline of the procedure is as follows. Different VNAs and different firmware versions might change the menu structure a little, but this should indicate the process.

Some standards are easier than others to define, as they have less parameters. In order of complexity, from the simplest to the most complicated, we have Loads - these are the easiest to define. Shorts Opens Since the opens are the most complicated things to define, this tutorial will define an open standard. The shorts and loads only have a subset of the parameters of the opens.

When the instrument is preset, the default calibration kit for the instrument will be loaded. You should see the normal calibration screen.

One part of the screen should show the currently loaded calibration kit, which, as stated above, will be the default kit.

You should now see a list of calibration kits. One, the default kit, in this example an series kit, will be underlined, as shown. Do not use the F kit if it is in the firmware. Even though the F is is an N kit, it is not a good choice to modify for our purposes, even if defining an N calibration kit.

The reason for this is the F has the same coefficients for the male and female standards, whereas most Agilent kits, and all Kirkby Microwave kits, do not have identical coefficients for the male and female standards. This is an easy mistake to make. People want to modify an open standard, so they press the OPEN softkey, which would then define standard 1 to be an open.

That would be bad news.

8753ES – Agilent

This model has four display channels. Every display channel has five markers that can be shown at the same time. Twenty independent markers can be shown in the four channel display mode if markers are uncoupled. The markers can be utilized for many functions such as: marker search, Mkr bandwidth with customized target values, Mkr to reference, trace statistics, Mkr to delay, and several more. The ES has options for a time-domain feature, harmonics measurement, a configurable test set, and the added capability to remove a test set.
