When working with high-performance electronic instruments, protecting them from potential damage is crucial. The Picotest Port Saver DC Block is specifically designed to meet this need, offering advanced protection features combined with excellent performance characteristics to safeguard your valuable equipment.
Keep Your Instruments Safe and Sound
One of the standout features of the Port Saver DC Block is its comprehensive transient protection. This device is like a bodyguard for your instruments, standing ready to fend off inrush surges and voltage spikes that could otherwise cause serious harm. The Port Saver has been rigorously tested against surge transients, ensuring reliable operation even when things get a bit dicey.
This level of protection isn’t just theoretical—take it from someone who’s been there. Just a few days ago, I was working with my $50k MXO5 scope, and let me tell you, I could have made a costly mistake. I was taking some measurements, and without the Picotest Port Saver, I could have easily blown up the front end of my scope. But thankfully, I had the Port Saver in place. It did exactly what it was designed to do—it failed safely, absorbing all that energy and protecting my scope from getting damaged. Considering that the repair would have set me back over $7,000, I was beyond relieved to have invested in a sub-$500 Port Saver. That little device saved me a ton of money and a lot of headaches.
And here’s where the Port Saver really shines: unlike typical RF blocks that suffer from AC and DC bias effects—making calibration a bit like trying to hit a moving target—the Port Saver eliminates these issues entirely. This means your measurements will be more accurate, and who doesn’t love accuracy?
Designed for Extra Protection and Performance
The Picotest Port Saver isn’t just about brute force protection; it’s smart, too. With self-charge and discharge capabilities, it’s like having a tech-savvy assistant who knows exactly when to power up and when to power down. These features allow the block to charge without being connected to an instrument and to discharge when disconnected from both the source and the instrument. This clever design prevents any potential damage from residual energy stored in the block—a bit like making sure the lights are off when you leave the room.
But protection is just one part of the equation. The Port Saver DC Block is also designed for top-notch performance. It operates quietly, ensuring minimal interference with your measurements, which is especially important in high-precision scenarios. Plus, it’s versatile. Whether you’re working with low frequencies or going up to 500 MHz, there’s a Port Saver model to fit the bill. Need a custom setup? No problem! The Port Saver can be tailored to your specific needs, with adjustable input voltage, clamp voltage, and frequency range.
The Right Model for Every Job
The Picotest Port Saver DC Block comes in two standard models: the P2131A and the P2132A, each suited to different tasks. The P2131A is the go-to choice for higher input voltages up to ±75V and covers a wide frequency range of 500Hz to 500MHz—perfect for when you need to cover a lot of ground. Meanwhile, the P2132A is designed for more specific, low-voltage applications, supporting input voltages up to ±4V and operating within a 2Hz to 50MHz frequency range. Both models offer low insertion loss and excellent VSWR, ensuring that they won’t cramp your style or your setup.
As shown below, Picotest Port Savers can be used easily with any oscilloscope, including the R&S MXO5 oscilloscope.
The Ultimate Instrument Protector
In summary, the Picotest Port Saver DC Block is like a superhero for your instruments—powerful, versatile, and always ready to protect. Whether you’re involved in power integrity measurements, signal integrity testing, or RF applications, the Port Saver ensures that your equipment stays safe and your measurements stay spot-on. After all, when it comes to your valuable instruments, why settle for anything less than the best protection?
