I'm confusing it with an HP Signal Schottky. I have the 1N5819 also for PSU applications. A full drawer of them. Memory playing tricks. Now that I'm reminded, I'd not even bother testing the 1N581x series
The actual HP/Aglient parts we tested as as Schottky signal diodes were probably the 5082-2835 and 5082-2800, certainly I still have some 5082-2800.
Definitely much poorer sensitivity than 1N60 for low level audio to 30MHz.
5082-2835 specs
PIV = 8
Vf = 340mV @ 1mA
Capacitance = 1pF
5082-2800 specs (similar to 1N5711)
PIV = 70
Vf= 410 @ 1mA
Capacitance=2pF
Unfortunately I recognised the number because I have that part.
The signal Shottkys will work to maybe 800MHz. The 5082-2800 is likely intended for UHF mixers as they come in matched pairs and quads (ring diode mixer needs four matched parts). The 5082-2835 as matched batches.
I may have a copy of the test data somewhere.
