I need to do power flatness calibration for 8510c since the gain of power amplifier varies about 4dB. My lab only has power meter 438A and power sensor 8481A, 8481H, 8485A. I check the application notes 8510-16, which suggest power meter 437B. I don't know whether 438A can handle this calibration. By the way, my 8510c has source 83621A and test set 8514B. Thanks.
