HP 10515A / Agilent 10515A Series 004 Frequency Doubler Input 0.5 to 500 MHz 180 MW max, Output 1.0 MHz to 1.0 GHz
This Frequency Doubler is an ideal accessory for use in extending the usable frequency range of signal generators, frequency synthesizers or other signal sources. This 50 ohm device uses a full-wave rectifier circuit which is extremely flat over its entire frequency range. the frequency response is very flat (< + 1 dB over entire range typically), and undesired harmonics are very well suppressed.

The output of this unit does not have an internal dc return, so that it will provide a very boadband ac to dc conversion only if not dc terminated. This mode of operation is useful for detection of low level amplitude modulations.

Connectors: Input - BNC Male, Output - BNC Female.

HP 11713A / Agilent 11713A Attenuator / Switch Driver with HP-IB
This instrument has all of the necessary features to provide HP-IB control of up to 2 programmable attenuators of the 8494/5/6/7 or 33321/1/2/3 series and concurrently up to 2 electro-mechanical switches. It can also be used to supply +24 V common and 10 pairs of transistor switches (total current less than 1.25A) to control up to 10 relays. This unit includes an integral power supply with short circuit protection that can simultaneously provide 125 mAmps at 24 V to all contacts for control of the attenuators & switches, so no external
power supply is needed.
