Hello,
My name is Azman and I am from Malaysia.
My superior at my work place asked me to find a spectrum analyzer that able to accept 1 kHz signal.
I found that N9010A EXA is the cheapest analyzer that have frequency range of 10Hz minimum.
While going through the data sheet, I found that the frequency response is 9kHz to 3.6GHz (with option 503) but the frequency range is 10Hz to 3.6GHz.
My question; is N9010 EXA with option 503 is suitable for us ?
Thanks.

First, let me suggest that you use the specifications guide (http://cp.literature.agilent.com/litweb/pdf/N9010-90025.pdf) rather than the data sheet when checking for specs. The guide is much more comprehensive and is updated regularly, which ensures that you will always have the most precise and accurate specification info available.
The N9010A indeed does work down to 10 Hz, as you mention. However, in the factory we do not test frequency response below 9 kHz. We do this to keep costs low. Adding flatness tests for the whole frequency range would require a lot of additional resources and time, which translates to a higher product cost.
I will emphasize that it _*is*_ possible to use the N9010A to make measurements at 1 kHz, but we do not guarantee a specific value for amplitude accuracy.
If it is absolutely necessary for you to have a warranted specification for frequency response at 1 kHz, you may want to consider a couple of other options. You may want to consider the N9020A MXA, which has specifications for frequency response at 1 kHz (see page 31 of the specifications guide: http://cp.literature.agilent.com/litweb/pdf/N9020-90113.pdf). Another, less expensive option would be the E4402B ESA-E (100 Hz to 3 GHz) with option UKB (start frequency extension). Page 22 of the specifications guide (http://cp.literature.agilent.com/litweb/pdf/E4401-90490.pdf) shows the frequency response specification down to 100 Hz. Note that the ESA specification is for worst case of +-0.5 dB for 20 to 30 degrees C, but the N9020A MXA has both a worst case value (+-0.6 dB) and a 95th percentile value (+-0.28 dB).
I hope this helps.
Please let me know if you have any additional questions.
