Sick 8709
Hello group! Anyone ever work on these? I have one that I am working on but having issues. #1, it says it's model 8709A on the front, but the manual for the 8709B appears closer. That is not helping.

8648C Sig Gen Question
I have an 8648C that I bought second hand, great Sig Gen. Yesterday I got in a new Siglent SSA3021X Spectrum Analyzer. I decided to run some tests on both. If I set the 8648c to -20dBm, I see -20.57

Re: N-Connectors at uW Frequencies
Take a look on E-bay for HP precision N to SMA bulkheAD CONNECTORS. i'VE BOUGHT THEM FOR AS LITTLE AS $10.00. Someone recently commented that the SWR input to the counter was about 4:1 - at that

Velocity of propagation (so I can determine insertion delay) for a 3.5mm coax adapter?
I'm trying to work out relationship of insertion delay (as measured with VNA in picoseconds) and insertion length (as might be specified for a device, in millimeters). My goal is to determine the

Re: N-Connectors at uW Frequencies
Hi From memory the Ebay price is the same as I was quoted as new several years ago I was thinking of them as an alternative to a replacement for broken APC 3.5 on the front of HP test equipment Best

Re: Question regarding HP 334A (Distortion Analyzer)
I checked the indicated transistors and they check good. HOWEVER: I noticed that if I change the frequency range switch to a different range, A5TP4 springs to life. Basically, if the input frequency

Re: N-Connectors at uW Frequencies
Hi Rainer In the past I have looked at Aeroflex Planar Crown but cannot remember how good they are compared to a APC 3.5 or a 2.92 connector Do you have any practical experience in using them also

Re: N-Connectors at uW Frequencies
Yup fully understand all this......even going to 22 GHz can be risky depending on what you are doing but using a N-connector at 26.5 GHz still puzzles me esp for later models made by Agilent. Not sure

Re: HP 4195A NiCad Battery replacement
Tobias, In the 4194A you can store 3 OSL cal data with frequency range, etc... That's an nice feature since it's ready, right from power on, with up to the 3 cal/config you need for the current job.

Re: HP 4195A NiCad Battery replacement
I am not an expert, but from what I have read, if you reduce reduce the charge current NiMH will be fine to replace NiCd. From memory C/20 is fine. You can achieve that by just using *high capacity*

Re: HP 53310A debugging
It's working! Interesting problem, never would have found it without the CLIPs. There are a number of voltage 'sub-regulators' and filters downstream of the main power supply. One filter, an inductor

Re: N-Connectors at uW Frequencies
You might note that many of the Hewlett Packard spectrum analyzers of the past, that went much higher than 18 GHz, use female type N connectors on their inputs; this includes the popular 8566A and B.

Re: HP 4195A NiCad Battery replacement
Correct - The reset circuit checks the battery voltage under charge. It measures the battery voltage and the charging current and suppresses the Reset signal for both CPUs. Cheers! Bruce Quoting

I didn't mean to hijack the thread "How to check the accuracy of an HP 5342A frequency counter". So I am starting a new thread. I will paste in what I placed in the other thread too.

Re: HP 4195A NiCad Battery replacement
I purchased two of these and will let you know if they are successful replacement. The part number to look for is COMP-34SPC of N-SP2 replacement. It is a 2.4V 90maHr NiCad. Cheers Quoting Tobias
