Product Description
The "GOLD PROBE" has been designed specifically for use with Tektronix, Hewlett Packard and other high performance oscilloscopes. This new slim design along with a host of versatile accessories, allows you to reach the most difficult test point in today's highly complex circuitry. The gold plated Probe Tips, Sprung Hook, Ground Lead & Alligator Tips provide excellent contacts for probing low level analog signals and high speed digital data. Unlike most "off shore" commodity probes, Probe Master guarantees quality and continuing domestic support for our "Made in America" Gold Probe.

**Readout Actuator (RA)
Available on 10X & 100X and Switchable 4900 series oscilloscope probes
RA Option for Tektronix 465, 475, 2200,2300, 2400, 5000, 7000, 11000 series scopes.
Not all scope are listed. Check your manuals or call us and we can help you determine if you scope has this option.
The READOUT ACTUATOR (RA), permanently attached at the factory, is an option for 10X, 100X and switchable probes. These RA probes may be used with the 465, 475, 2200, 2300, 2400, 5000, 7000 and 11000 series Tektronix scopes. This option eliminates the need to divide by the attenuation ratio or remember which probe is being used. The readout actuator allows you to read your measurements directly from the oscilloscope screen.

250 Mhz 10x 4905-1 probe
I've tested many different passive probes (ebay cheapo's to tektronix) and I am very pleased with the probemaster 4900 series. No question, all future passive probes I buy will be directly from probe master. Not only was the 4900 easier to work with than my other brands (basic clamping and maneuvering), but once it's tuned in, it has lower noise than comparable 10x probes (better than my Tek TP0101). I mean, 11pF circuit loading @ 250 Mhz for $56, how can you lose? My only sort of complaint would be the length of the 4905-1. It is completely sufficient for normal bench uses, but if you were working on a more distant circuit, it might become an issue. Perhaps for the next one I go with a 4905-2 for the extra length and accept the 1pF loading gain lol. The cable is also slightly less flexible than others i've worked with. That said, totally acceptable for the performance and characteristics previous described! Enjoy!

oscilloscope probe
I received the probe promptly. It seems to be of good quality and so far it has worked well with my scope.

4900 Probe and Customer Service
I wanted a 1x/10x switchable probe to use with a TDS460 scope, and this works very well. I want to complement Probemaster on their customer service. The probe was not working when I got it (open connection). Sent Probemaster an email and within one day they they had sent me a replacement. Got it in two days and this one has been working ever since.

4900 O'Scope Probe
We are a R&D/Contract provider. We have several equipment installations in the field and these probes get constant use, misuse and abuse. They hold up amazingly well and provide accurate measurement and monitoring of critical signal parameters to ensure top equipment performance. The performance/quality of the probes vs. cost represents an exceptional value as well. Thanks for reading. I have received no monetary or material compensation for this endorsement.

100x probe
This probe worked very well to enable testing of a universal AC input flyback converter design at high line. I used it with an Agilent scope.
