Environmental characteristics
General conditions
RFI and EMI susceptibility: defined by VDE 0730,
CISPR Publication 11, and FCC Class B Standards.
ESD (electrostatic discharge): must be eliminated by
use of static-safe work procedures and an anti-static
bench mat. The flexible rubber keypad protects key
contacts from dust, but the environment should be as
dust-free as possible for optimal reliability.

Options
Harmonic measurements (Option 002)
Measures amplifier 2nd and 3rd harmonics on a swept-
frequency basis for fundamental signals above 16 MHz.
Dynamic range (source at +10 dBm,
receiver <+30 dBm) +40 dBc (minimum)
Accuracy
5
±1 dB (< 6 GHz)
Step attenuator (Option 004)
Provides source output power range from
-85 to +10 dBm for HP 8753ET model.
6 GHz operation (Option 006)
With Option 006, performance is extended to 6 GHz.
When external source, tuned receiver or harmonic
mode is used, the receiver is capable of measuring sig-
nals up to 6 GHz.
Time domain (Option 010)
Transforms data from the frequency domain to the
time domain using a Fourier transformation technique.
High-stability frequency reference (Option 1D5)
This option adds an ovenized 10-MHz frequency refer-
ence output. It is connected to the external reference
input on the rear panel. See the “General
Characteristics” section for below specifications.
1. One-port calibration, with a 6 kHz IF bandwidth. Includes system retrace time, but
does not include bandswitch time. Time-domain gating is assumed off.
2. Same as footnote 1, but for an S21 measurement with full two-port calibration. Includes RF switching time.
3. Option 010 only, gating off.
4. Measured with an HP Omnibook 7100 266 MHz Pentium
®
II computer.
5. Does not include error from the HP 8753T/ES source and receiver harmonics.
