Re: Power indicator lamps
Hi Dan and list.
I'm posting this on list so I can correct something I posted last week. The lamps arrived today and I give positive feedback and much thanks to Dan. Now to the list I had stated that the lamps were solder in. I say in my defense that the lamp in the Boonton 250A is hidden behind the fuse holder and power switch. The one in the HP 712B is in a deep dark hole. As it turns out the two pins slip into a socket of sorts. I wonder why HP selected that type of lamp instead of an almost universal standard number 47 bayonet lamp. Oh, well, they did what they did. The lamp in the 712B is especially important because it annunciates the high voltage being on. The voltmeter on the power supply reads continuously and the HV path is interrupted by a relay that is between the regulator output and the output binding post. The relay is controlled by a toggle switch. If a user thought the HV was off when in reality it was on, well... 500 volts at 200 mA is nothing to be casual about.

Re: Length of "standard" section in the X11644A calibration kit for WR90 waveguide
The WG section looks to be the same length as the 50 Ohm WG termination.
I'd expect a common part would be used for both parts. Check the parts
lists, compare part numbers, and measure yours.
Also, the Agilent site has parameter files. You should be able to compute
the length and convert to physical guide length for the test frequency.
Finally, ask on the Agilent forum.
FWIW,
-John

8690 plugins and more boatanchors
I'm helping with the getting a large collection of equipment and parts up for sale. The smaller stuff will go on a store and the E.
But I need to start clearing out some of the bigger older true
boat anchors.
In the first pass there are a large number of 8690 plugins, if there
is any interest let me know.
Make an offer, if you close to NW Oregon I can bring them to the
Seaside ham fair in June, if not I can take more pictures but please
remember shipping costs.
So far I have not found a frame to plug them into.

Hi J
Hard to say, need to ask.
Their website doesn't work very well
Some of their parts go down to 1.3 db at 8 ghz. No reason to expect low
noise figure from a device that doesn't brag about it. There are lots of
other parameters they can choose to optimize. They do make low noise amps
in that package
In ancient times I used to kinda work for these guys in a backhanded way.
I sent AML an RFQ.

Re: 85685A special cabling changes
Bill,
?????? I just bought (and also had to repair the preselector)
Out of interest? I tried it without the cable, and it worked without complaint.
It seemed like there was some switch glitch on the display, at a part of the scan though. Will look into it later when I adapt the cable.

?
The Spec An / Preselector combination does not work without the HSWP connection. There is an error that announces the lack of the connection and the instrument will not go beyond that point.
As far as the two cable types with the different HSWP pickoff, there is no apparent difference in the functionality or effect on measurement accuracy. I had a set of the 8574A cables that had the pickoff on the cable connector side and used that set for performance testing of all vintages of the system when the customer cables were not shipped with the unit.

David,
just for future reference, there is absolutely no reason why you need to
pay 60GBP to ship an item like this. I checked my usual shipping agent
for a weight of 36kg (33kg + 3kg of packing, which is a guess), and the
best quote was 14.69GBP for an overnight service to mainland UK. That
includes VAT, but not extra insurance (if needed). That was from
Parcel Monkey - see (I have no connection
with the company except as a reasonably happy customer).
I note lots of sellers on Ebay lose out because they have a heavy item,
which they assume will cost megabucks to ship. They are wrong, and the
lose out by restricting themselves to only those who will collect.
best wishes
Richard

Re: For Sale 4 each. 1164A Miniature Passive Probe, 10:1, 10 MOhm, 1.5 m
Right...It's a slow speed analog signal with no need for any special handling. You could use lamp cord and an RCA jack if you wanted to. HP just picked an SMA out of convenience.

Re: New USB to GPIB Board - Galvant Industries - Anyone tried this?
You can push 3 Mbits/s through FT232RL. It does a fine job sustaining that transfer
rate when you use D2XX API. I doubt it could ever be a limitation when GPIB is involved.

Just wondering if anyone has new of this one. Sure looks sweet for the

Seems a bit round about in its implementation to use an FTDI FT232RL
USB-Serial chip to internally connect to a PIC18F4520 which interfaces
to the GPIB bus. I suppose that might simplify the driver
requirements on the host computer and allow the use of generic FTDI
USB serial drivers. I wonder how the internal serial communications
of this adapter limits its throughput?
