1. Can you explain the different symbols found within the GUI test results?
There are 4 icons that you may see while running tests within the GUI that indicate the success/failure of each execution within a test run.
A green checkmark – indicates that all the data points within that test fell within the expected min and max value.
A yellow caution icon – indicates that some of the data points fell within the expected min and max value, but other data points exceeded those values.
A red circle with slash – indicates that none of the data points within the test met the expected min and max values.
A red circle with an ‘X’ in the middle – indicates that an error occurred while running the test
2. I am unable to log into my Progranalog LoadSlammer account, how do I fix this?
Some internet providers block connections to unknown outside sources. Adding the below host URLs to your providers whitelist should resolve this issue.
3. USB device is not recognized, how do I connect?
First, confirm that your USB drivers are at the latest version. If using Windows 7, please see question 14 below.
If you are still experiencing connection issues, a USB HUB device can be used to resolve the issue.
4. How many Vrails can be supported on a 45 x 45 passive adaptor?
This depends on the size of the rails, but typically our 45 x 45 passive adaptor supports 2-3 large rails and about 10 smaller rails.
5. Does a LoadSlammer device support 12V?
Our current family of devices support 0.5V to 2.0V, but our team is working on LoadSlammers that can support 2V through to 110V. Please refer to our LoadSlammer Pro User Guide to see operating specifications for our current models or ask for updated status information.
6. Will I be notified if there is new GUI to download?
Our team is currently working on setting up a process to notify users when a new GUI is available.
7. What is the typical rise time of the Slammer?
The rise time varies based on the slammer, but the typical rise time is less than 200 nanoseconds. Refer to our LoadSlammer Pro User Guide to see operating specifications for our current models.
8. What is the Offset option in the LoadSlammer GUI?
The offset setting in our LoadSlammer GUI is a DC offset applied to the transient test, similar to the DC offset found on a function generator. We recommend keeping the offset at 0A if you do not need a specific DC offset in your tests.
9. Do active modules have faster rise times?
Yes, faster rise times are typically seen on active modules because the PDN has less inductance.
10. Can you explain how over temperature monitoring works?
Our devices have temperature sensors that monitor the temperature of the transistors and automatically shuts down the slammer if the temperature gets too high. It also requires that the temperature drops below a threshold before slamming again.
11. What do the LoadSlammer LED colors mean?
Below indicate what each color option means on the LoadSlammer devices.
Green – Adapter detected
Blue – Device is actively Slamming
Red – Error Occurred
Purple/white – Error occurred while device was slamming
Yellow – Adapter detected, but an error occurred
12. How do you configure GUI to support adjustable slew rate?
The LoadSlammer ADJ offers full support for adjustable slew rates.
13. Is duty cycle set in fixed steps or can you preset arbitrary values?
Currently our duty cycles are set but our team has plans on building functionality that allows for users to control the duty cycle values in the future.
14. Can multiple slammers be synchronized?
The LoadSlammer Pro 1000 and LoadSlammer Pro 1000RS allow parallel of multiple devices to support high current requirements. A parallel cable is required to link the devices together.
15. Our machine runs on Windows 7, how do we install the drivers for the latest GUI version?
The link below provides instructions on installing the necessary drivers for using the LoadSlammer GUI.
16. While using a protector, we noticed a difference between our scope capture via an oscilloscope and the LoadSlammer GUI. Why is there a difference?
Through our testing we have found there is a small amount of resistance from the Protector PCBs that can cause more of a Vdroop and slow the edge rate. The LS-Protector regular has about 1/3rd of the resistance compared to the Protector-Mini due to the larger surface area in parallel. If the scope measurements are probed before the Protector PCB, this could explain the Vdroop differences. Keep in mind the LSP Mini‘s and 1000RS have a 5% Current Output Accuracy through the SMB outputs that will also explain the slight difference between scope capture and GUI results.
17. What is the max voltage that can be tested?
18. What is the SMB Current Scaling?
The SMB current scaling is 20mV/A. This can also be confirmed by double-clicking any waveform result, a pop-up will appear showing the waveform information along with amps per volt, sample rate and parallel count.
