RF Survey Equipment
I received this price quote from Narda. Seems like a good equipment, but
quite pricey.

>Hi Rick,
>Thank you for contacting the Narda Microwave web site regarding RF Safety
>Products. Per you inquiry for making measurements in multi-emitter
>environments, we offer RF Survey Systems specifically designed for this
>application.
>
>The probes designed for this environment read out in Percent of Standard as
>opposed to power density. The reason for this is that different frequencies
>have different MPE (Maximum Permissible Exposure) limits. For example; you
>have two transmitting antennas on your rooftop, one at 800MHz, whose MPE
>limit for the FCC OET Bulletin 65 Standard is 2.67mW/cm2 and one at 1.9GHz
>whose MPE limit is 5mW/cm2. If the meter is reading 3.5mW/cm2(power
>density) you will NOT be able to determine if you are within the limits of
>the standard. This is because you will not be able to determine what each
>individual antennas contribution to the reading is.
>
>We have two probes to offer that are used specifically for compliance to the
>FCC OET Bulletin 65 Standard. One of these is model A8742D which is an
>E-field probe that operates from 300KHz to 3GHz. The other is the A8722D
>which is also an E-field probe. This model operates from 300KHz to 50GHz.
>The A8722D probe would cover the frequency range of any microwave antennas
>that could be present on your rooftops. Both probes can be used with any of
>the 8700 series of hand held digital meters. The meters I would recommend
>for your application would be either model 8712 or model 8715. The only
>difference between the two meters is that the 8715 has the capability to do
>spatial averaging.
>
>The prices for the probes and meters mentioned above are as follows:
>
>A8742D Probe $3,900
>A8722D Probe $5,200
>8712 Meter $2,350
>8715 Meter $3,950

>If you have any questions regarding any of the equipment, please don't
>hesitate to contact me.
