I need to ID the HP part number 1826-0092, a dual opamp in TO-99. I think it may be a common, nothing special type like LM358 or 1458. It's an oldie, and I haven't been able to find it in any of the HP cross-reference lists I've found. It is in spot U17 on A22 of an HP8568A. The board layout can take a DIP too, so no big deal - I've got lots of parts in stock to choose from once I figure out what it's supposed to be. I suspect I have burned it out due to mis-connecting my home-made interface between the RF and the IF/display units - long story that I'll relate later.

Does anyone know what this is?

> Have you looked at the copy of the 400E/EL manual on the Keysight site

Thanks for the suggestion. I once imagined that the E/EL and F/FL differed mainly by the F's extended range and low pass filter, but I discovered that they are in fact different animals, each with their own main boards.

Have you looked at the copy of the 400E/EL manual on the Keysight site? That copy has a printing date of Mar-1986 and has change sheets dated as late as 1984. The 400F manual there is what you have.

Hi...My IC list says I have several of these....(been wrong before, but likely I have these).
Don't have a clue what the actual part number is...

Contact me off line if interested.

For starters I Only have a 1968 Copy of the manual at the moment. Serial prefix 2213A is the last week of March (13th week) of 1982.

My guess is that 1980 was around the time that the internal model number (serial number prefix) changed from 0950A to 2213A.
The later 400 F manual editions would have the newer 00400-66514 A2 board schematic, which is not shown in the earlier manuals. Thanks again.

1. Quan (300). 12" long, RG-214, Male-N (straight) to Male-N (90-degree) with Huber-Suhner connectors ! $40 for 5.

2. Quan (20) Flexible solid semi-rigid Female-N to Male-SMA jumpers (asst lengths, ave ~12"-~20"), These use Huber-Suhner connectors (excellent quality). Also the semi-rigid coax can be soldered to using normal solder which means the coax and/or connectors can be re-used ! $4.50/each


3. Quan (50) Flexible solid semi-rigid Male-N to Male-SMA jumpers (asst lengths, ave ~12"-~20"), These use Huber-Suhner connectors (excellent quality).? Also the semi-rigid coax can be soldered to using normal solder which means the coax and/or connectors can be re-used !? $4.50/each

4. Quan (35) Brand New, Mini-Circuit 12 dB N-Female to N-Male connectors, DC-6 GHz. Swept these and these are SPOT on ! Really excellent attenuators. $10/each.


5. Quan (14). INMET Model 3070M, DC-18 GHz terminations NOS in plastic bags. Will handle 2 watts, $12/ea.

6. Quan (2), Radial high-performance SP6T uW relays w/LED indicators. Rated at 240 watts (ave pwr) up to 3 GHz, and 100 Watts (ave pwr) up at 18 GHz, port-to-port isolation of 80 dB (down to 60 dB at 18 GHz). The coils draw about 100 mA and each relay contact is rated for up to 5 million cycles.

What makes these relays really neat is that they have a small PCB mounted to the contacts already ! The PCB uses a standard 2 mm, 20-pin DIP connector to access all of the required contacts and there are 6 LED's that indicate which port is being energized. Last two available, $25/each.





7. Quan (16) same relays as above but with NO LCD PWB mounted on relay.....$16/each.

8. Quan (40) Anritsu Dual-Coil "Quasi SPDT" 13 GHz SMA relays. What makes these relays fascinating is the way the contacts can be energized. The control connector is a 3-pin Molex type. The center pin is common. One side of center will energize one coil, the other side will energize the other coil. In the un-energized condition the two "output" ports are tied together and grounded. As soon as one side is energized a connection is made between the common SMA port and one output SMA port. One or two ports can be connected to the input (common) SMA port. Because this relay has two independent coils (one for each port) you can energize one coil, or two, and use the relay in a number of different ways. Either AC or DC can be used & the coil draws about 30 mA at 12 VDC. Will pull in as low as around 6-7 VDC and not get as warm. They have a very nice 1/8" thick aluminum mounting plate making mounting them a snap. $12/each.







PayPal or personal/company check aok as always. All I ask is if you tell me you want something PSE be prepared to let me know ASAP & be prepared to pay for your item(s).

Re: survey of 400 E and 400 F service manual editions?

 

About all you can do is to find a manual and make your own list of every series included in the manual and its change sheets. Then survey units for sale (eBay and others) and add their series prefix numbers to,your list. That's about the only way to get a list, unless you run across an aficionado who has a collection.

Ed,

From a repair thread on EEVBlog the fellow replaced the 1826-0092 with a LM1558H to get his supply working.

HP 16505A Operating System Upgrade

 

I am in the process of trying to update the operating system for the HP 16505A to use HPUX 10.20 or later versus the HPUX 9.05 it was supplied with and have run into an issue with the original HPUX 9.05 vs 10.20 SCSI Passthrough Driver.

In particular the HP 16505A is a dedicated workstation (same as a HP 712/100) that was to hooked up to a HP 16500B/C Logic Analyzer via the external SCSI interface to provide the analysis tools for the analyzer.

The original software supplied in the HP 16505A was HPUX 9.05 and was tailored to only run the analysis program (vp) for the analyzer. It was very easy to gain access to the OS via the IPL and setup a root account. So easy to see how it was setup.

What I found was that the analysis program used the SCSI passthrough driver SCTL to provide the I/O to the analyzer. Running an ioscan on the HPUX 9.05 OS showed the analyzer as a scanner. Not sure why at this point but it was at the correct address. In addition the device nodes used are /dev/scsi/0 - 6 and used the major device 105 which was the scsi passthrough driver. Since the dedicated software to control the analyzer is easy to partition out of the base system, I wanted to see if I could upgrade to 10.20 or even 11 and get the analysis software to work on the upgraded OS. So I did a cold install of 10.20 with no issues. I was also able to transplant the analysis software without issue. I also recreated the /dev/scsi/0 - 6 using the new major device of 203 via mknod which is for the passthrough driver in 10.20.

The problem I am having is that when I hookup the analyzer and do a ioscan the OS hangs with ibolt errors recorded in the syslog. ioscan is hanging up on the analyzer address. Same happens during a cold boot. The OS hangs for about 5 min and then proceeds. The results from ioscan on 10.20 do not show the analyzer at all.

Does anyone know what the difference is between the SCSI drivers between 9.05 and 10.20 that might give me some hope of getting this working as it seems that something changed in the SCSI drivers between 9.05 and 10.20.
